The 3c509 was written by Donald Becker between 1993-2000. It is an ISA
device, so unlikely to be used with modern kernels.

-
- Known limitations:
- Because of the way 3c509 ISA detection works it's difficult to predict
- a priori which of several ISA-mode cards will be detected first.
-
- This driver does not use predictive interrupt mode, resulting in higher
- packet latency but lower overhead. If interrupts are disabled for an
- unusually long time it could also result in missed packets, but in
- practice this rarely happens.
-
-
- FIXES:
- Alan Cox: Removed the 'Unexpected interrupt' bug.
- Michael Meskes: Upgraded to Donald Becker's version 1.07.
- Alan Cox: Increased the eeprom delay. Regardless of
- what the docs say some people definitely
- get problems with lower (but in card spec)
- delays
- v1.10 4/21/97 Fixed module code so that multiple cards may be detected,
- other cleanups. -djb
- Andrea Arcangeli: Upgraded to Donald Becker's version 1.12.
- Rick Payne: Fixed SMP race condition
- v1.13 9/8/97 Made 'max_interrupt_work' an insmod-settable variable -djb
- v1.14 10/15/97 Avoided waiting..discard message for fast machines -djb
- v1.15 1/31/98 Faster recovery for Tx errors. -djb
- v1.16 2/3/98 Different ID port handling to avoid sound cards. -djb
- v1.18 12Mar2001 Andrew Morton
- - Avoid bogus detect of 3c590's (Andrzej Krzysztofowicz)
- - Reviewed against 1.18 from scyld.com
- v1.18a 17Nov2001 Jeff Garzik <jgarzik@pobox.com>
- - ethtool support
- v1.18b 1Mar2002 Zwane Mwaikambo <zwane@commfireservices.com>
- - Power Management support
- v1.18c 1Mar2002 David Ruggiero <jdr@farfalle.com>
- - Full duplex support
- v1.19 16Oct2002 Zwane Mwaikambo <zwane@linuxpower.ca>
- - Additional ethtool features
- v1.19a 28Oct2002 Davud Ruggiero <jdr@farfalle.com>
- - Increase *read_eeprom udelay to workaround oops with 2 cards.
- v1.19b 08Nov2002 Marc Zyngier <maz@wild-wind.fr.eu.org>
- - Introduce driver model for EISA cards.
- v1.20 04Feb2008 Ondrej Zary <linux@rainbow-software.org>
- - convert to isa_driver and pnp_driver and some cleanups

The 3c515 was written by Donald Becker between 1997-1998. It is an ISA
device, so unlikely to be used with modern kernels.

- Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the 3Com 3c515 ISA Fast EtherLink XL,
-3Com's ISA bus adapter for Fast Ethernet. Due to the unique I/O port layout,
-it's not practical to integrate this driver with the other EtherLink drivers.
-
-II. Board-specific settings
-
-The Corkscrew has an EEPROM for configuration, but no special settings are
-needed for Linux.
-
-III. Driver operation
-
-The 3c515 series use an interface that's very similar to the 3c900 "Boomerang"
-PCI cards, with the bus master interface extensively modified to work with
-the ISA bus.
-
-The card is capable of full-bus-master transfers with separate
-lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
-DEC Tulip and Intel Speedo3.
-
-This driver uses a "RX_COPYBREAK" scheme rather than a fixed intermediate
-receive buffer. This scheme allocates full-sized skbuffs as receive
-buffers. The value RX_COPYBREAK is used as the copying breakpoint: it is
-chosen to trade-off the memory wasted by passing the full-sized skbuff to
-the queue layer for all frames vs. the copying cost of copying a frame to a
-correctly-sized skbuff.
-
-
-IIIC. Synchronization
-The driver runs as two independent, single-threaded flows of control. One
-is the send-packet routine, which enforces single-threaded use by the netif
-layer. The other thread is the interrupt handler, which is single
-threaded by the hardware and other software.
-
-IV. Notes
-
-Thanks to Terry Murphy of 3Com for providing documentation and a development
-board.
-
-The names "Vortex", "Boomerang" and "Corkscrew" are the internal 3Com
-project names. I use these names to eliminate confusion -- 3Com product
-numbers and names are very similar and often confused.
-
-The new chips support both ethernet (1.5K) and FDDI (4.5K) frame sizes!
-This driver only supports ethernet frames because of the recent MTU limit
-of 1.5K, but the changes to support 4.5K are minimal.

The 3c574 was written by Donald Becker between 19973-1998. It is an
PCMCIA device, so unlikely to be used with modern kernels.

-/* 3c574.c: A PCMCIA ethernet driver for the 3com 3c574 "RoadRunner".

- Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the 3Com 3c574 PC card Fast Ethernet
-Adapter.
-
-II. Board-specific settings
-
-None -- PC cards are autoconfigured.
-
-III. Driver operation
-
-The 3c574 uses a Boomerang-style interface, without the bus-master capability.
-See the Boomerang driver and documentation for most details.
-
-IV. Notes and chip documentation.
-
-Two added registers are used to enhance PIO performance, RunnerRdCtrl and
-RunnerWrCtrl. These are 11 bit down-counters that are preloaded with the
-count of word (16 bits) reads or writes the driver is about to do to the Rx
-or Tx FIFO. The chip is then able to hide the internal-PCI-bus to PC-card
-translation latency by buffering the I/O operations with an 8 word FIFO.
-Note: No other chip accesses are permitted when this buffer is used.
-
-A second enhancement is that both attribute and common memory space
-0x0800-0x0fff can translated to the PIO FIFO. Thus memory operations (faster
-with *some* PCcard bridges) may be used instead of I/O operations.
-This is enabled by setting the 0x10 bit in the PCMCIA LAN COR.
-
-Some slow PC card bridges work better if they never see a WAIT signal.
-This is configured by setting the 0x20 bit in the PCMCIA LAN COR.
-Only do this after testing that it is reliable and improves performance.
-
-The upper five bits of RunnerRdCtrl are used to window into PCcard
-configuration space registers. Window 0 is the regular Boomerang/Odie
-register set, 1-5 are various PC card control registers, and 16-31 are
-the (reversed!) CIS table.
-
-A final note: writing the InternalConfig register in window 3 with an
-invalid ramWidth is Very Bad.
-

The 3c59x was written by Donald Becker between 1996-1999. It is an
EISA and PCI Fast Ethernet device, so unlikely to be used with modern
kernels.

-Module parameters
-=================
-
-There are several parameters which may be provided to the driver when
-its module is loaded. These are usually placed in ``/etc/modprobe.d/*.conf``
-configuration files. Example::
-
- options 3c59x debug=3 rx_copybreak=300
-
-If you are using the PCMCIA tools (cardmgr) then the options may be
-placed in /etc/pcmcia/config.opts::
-
- module "3c59x" opts "debug=3 rx_copybreak=300"
-
-
-The supported parameters are:
-
-debug=N
-
- Where N is a number from 0 to 7. Anything above 3 produces a lot
- of output in your system logs. debug=1 is default.
-
-options=N1,N2,N3,...
-
- Each number in the list provides an option to the corresponding
- network card. So if you have two 3c905's and you wish to provide
- them with option 0x204 you would use::
-
- options=0x204,0x204
-
- The individual options are composed of a number of bitfields which
- have the following meanings:
-
- Possible media type settings
-
- == =================================
- 0 10baseT
- 1 10Mbs AUI
- 2 undefined
- 3 10base2 (BNC)
- 4 100base-TX
- 5 100base-FX
- 6 MII (Media Independent Interface)
- 7 Use default setting from EEPROM
- 8 Autonegotiate
- 9 External MII
- 10 Use default setting from EEPROM
- == =================================
-
- When generating a value for the 'options' setting, the above media
- selection values may be OR'ed (or added to) the following:
-
- ====== =============================================
- 0x8000 Set driver debugging level to 7
- 0x4000 Set driver debugging level to 2
- 0x0400 Enable Wake-on-LAN
- 0x0200 Force full duplex mode.
- 0x0010 Bus-master enable bit (Old Vortex cards only)
- ====== =============================================
-
- For example::
-
- insmod 3c59x options=0x204
-
- will force full-duplex 100base-TX, rather than allowing the usual
- autonegotiation.
-
-global_options=N
-
- Sets the ``options`` parameter for all 3c59x NICs in the machine.
- Entries in the ``options`` array above will override any setting of
- this.
-
-full_duplex=N1,N2,N3...
-
- Similar to bit 9 of 'options'. Forces the corresponding card into
- full-duplex mode. Please use this in preference to the ``options``
- parameter.
-
- In fact, please don't use this at all! You're better off getting
- autonegotiation working properly.
-
-global_full_duplex=N1
-
- Sets full duplex mode for all 3c59x NICs in the machine. Entries
- in the ``full_duplex`` array above will override any setting of this.
-
-flow_ctrl=N1,N2,N3...
-
- Use 802.3x MAC-layer flow control. The 3com cards only support the
- PAUSE command, which means that they will stop sending packets for a
- short period if they receive a PAUSE frame from the link partner.
-
- The driver only allows flow control on a link which is operating in
- full duplex mode.
-
- This feature does not appear to work on the 3c905 - only 3c905B and
- 3c905C have been tested.
-
- The 3com cards appear to only respond to PAUSE frames which are
- sent to the reserved destination address of 01:80:c2:00:00:01. They
- do not honour PAUSE frames which are sent to the station MAC address.
-
-rx_copybreak=M
-
- The driver preallocates 32 full-sized (1536 byte) network buffers
- for receiving. When a packet arrives, the driver has to decide
- whether to leave the packet in its full-sized buffer, or to allocate
- a smaller buffer and copy the packet across into it.
-
- This is a speed/space tradeoff.
-
- The value of rx_copybreak is used to decide when to make the copy.
- If the packet size is less than rx_copybreak, the packet is copied.
- The default value for rx_copybreak is 200 bytes.
-
-max_interrupt_work=N
-
- The driver's interrupt service routine can handle many receive and
- transmit packets in a single invocation. It does this in a loop.
- The value of max_interrupt_work governs how many times the interrupt
- service routine will loop. The default value is 32 loops. If this
- is exceeded the interrupt service routine gives up and generates a
- warning message "eth0: Too much work in interrupt".
-
-hw_checksums=N1,N2,N3,...
-
- Recent 3com NICs are able to generate IPv4, TCP and UDP checksums
- in hardware. Linux has used the Rx checksumming for a long time.
- The "zero copy" patch which is planned for the 2.4 kernel series
- allows you to make use of the NIC's DMA scatter/gather and transmit
- checksumming as well.
-
- The driver is set up so that, when the zerocopy patch is applied,
- all Tornado and Cyclone devices will use S/G and Tx checksums.
-
- This module parameter has been provided so you can override this
- decision. If you think that Tx checksums are causing a problem, you
- may disable the feature with ``hw_checksums=0``.
-
- If you think your NIC should be performing Tx checksumming and the
- driver isn't enabling it, you can force the use of hardware Tx
- checksumming with ``hw_checksums=1``.
-
- The driver drops a message in the logfiles to indicate whether or
- not it is using hardware scatter/gather and hardware Tx checksums.
-
- Scatter/gather and hardware checksums provide considerable
- performance improvement for the sendfile() system call, but a small
- decrease in throughput for send(). There is no effect upon receive
- efficiency.

-
- Sets enable_wol mode for all 3c59x NICs in the machine. Entries in

-
-Media selection
----------------
-
-A number of the older NICs such as the 3c590 and 3c900 series have
-10base2 and AUI interfaces.
-
-Prior to January, 2001 this driver would autoselect the 10base2 or AUI
-port if it didn't detect activity on the 10baseT port. It would then
-get stuck on the 10base2 port and a driver reload was necessary to
-switch back to 10baseT. This behaviour could not be prevented with a
-module option override.
-
-Later (current) versions of the driver _do_ support locking of the
-media type. So if you load the driver module with
-
- modprobe 3c59x options=0
-
-it will permanently select the 10baseT port. Automatic selection of
-other media types does not occur.
-
-
-Transmit error, Tx status register 82
--------------------------------------
-
-This is a common error which is almost always caused by another host on
-the same network being in full-duplex mode, while this host is in
-half-duplex mode. You need to find that other host and make it run in
-half-duplex mode or fix this host to run in full-duplex mode.
-
-As a last resort, you can force the 3c59x driver into full-duplex mode
-with
-
- options 3c59x full_duplex=1
-
-but this has to be viewed as a workaround for broken network gear and
-should only really be used for equipment which cannot autonegotiate.

-Autonegotiation notes
----------------------
-
- The driver uses a one-minute heartbeat for adapting to changes in
- the external LAN environment if link is up and 5 seconds if link is down.
- This means that when, for example, a machine is unplugged from a hubbed
- 10baseT LAN plugged into a switched 100baseT LAN, the throughput
- will be quite dreadful for up to sixty seconds. Be patient.
-
- Cisco interoperability note from Walter Wong <wcw+@CMU.EDU>:
-
- On a side note, adding HAS_NWAY seems to share a problem with the
- Cisco 6509 switch. Specifically, you need to change the spanning
- tree parameter for the port the machine is plugged into to 'portfast'
- mode. Otherwise, the negotiation fails. This has been an issue
- we've noticed for a while but haven't had the time to track down.
-
- Cisco switches (Jeff Busch <jbusch@deja.com>)
-
- My "standard config" for ports to which PC's/servers connect directly::
-
- interface FastEthernet0/N
- description machinename
- load-interval 30
- spanning-tree portfast
-
- If autonegotiation is a problem, you may need to specify "speed
- 100" and "duplex full" as well (or "speed 10" and "duplex half").
-
- WARNING: DO NOT hook up hubs/switches/bridges to these
- specially-configured ports! The switch will become very confused.
-
-
-Reporting and diagnosing problems
----------------------------------
-
-Maintainers find that accurate and complete problem reports are
-invaluable in resolving driver problems. We are frequently not able to
-reproduce problems and must rely on your patience and efforts to get to
-the bottom of the problem.
-
-If you believe you have a driver problem here are some of the
-steps you should take:
-
-- Is it really a driver problem?
-
- Eliminate some variables: try different cards, different
- computers, different cables, different ports on the switch/hub,
- different versions of the kernel or of the driver, etc.
-
-- OK, it's a driver problem.
-
- You need to generate a report. Typically this is an email to the
- maintainer and/or netdev@vger.kernel.org. The maintainer's
- email address will be in the driver source or in the MAINTAINERS file.
-
-- The contents of your report will vary a lot depending upon the
- problem. If it's a kernel crash then you should refer to
- 'Documentation/admin-guide/reporting-issues.rst'.
-
- But for most problems it is useful to provide the following:
-
- - Kernel version, driver version
-
- - A copy of the banner message which the driver generates when
- it is initialised. For example:
-
- eth0: 3Com PCI 3c905C Tornado at 0xa400, 00:50:da:6a:88:f0, IRQ 19
- 8K byte-wide RAM 5:3 Rx:Tx split, autoselect/Autonegotiate interface.
- MII transceiver found at address 24, status 782d.
- Enabling bus-master transmits and whole-frame receives.
-
- NOTE: You must provide the ``debug=2`` modprobe option to generate
- a full detection message. Please do this::
-
- modprobe 3c59x debug=2
-
- - If it is a PCI device, the relevant output from 'lspci -vx', eg::
-
- 00:09.0 Ethernet controller: 3Com Corporation 3c905C-TX [Fast Etherlink] (rev 74)
- Subsystem: 3Com Corporation: Unknown device 9200
- Flags: bus master, medium devsel, latency 32, IRQ 19
- I/O ports at a400 [size=128]
- Memory at db000000 (32-bit, non-prefetchable) [size=128]
- Expansion ROM at <unassigned> [disabled] [size=128K]
- Capabilities: [dc] Power Management version 2
- 00: b7 10 00 92 07 00 10 02 74 00 00 02 08 20 00 00
- 10: 01 a4 00 00 00 00 00 db 00 00 00 00 00 00 00 00
- 20: 00 00 00 00 00 00 00 00 00 00 00 00 b7 10 00 10
- 30: 00 00 00 00 dc 00 00 00 00 00 00 00 05 01 0a 0a
-
- - A description of the environment: 10baseT? 100baseT?
- full/half duplex? switched or hubbed?
-
- - Any additional module parameters which you may be providing to the driver.
-
- - Any kernel logs which are produced. The more the merrier.
- If this is a large file and you are sending your report to a
- mailing list, mention that you have the logfile, but don't send
- it. If you're reporting direct to the maintainer then just send
- it.
-
- To ensure that all kernel logs are available, add the
- following line to /etc/syslog.conf::
-
- kern.* /var/log/messages
-
- Then restart syslogd with::
-
- /etc/rc.d/init.d/syslog restart
-
- (The above may vary, depending upon which Linux distribution you use).
-
- - If your problem is reproducible then that's great. Try the
- following:
-
- 1) Increase the debug level. Usually this is done via:
-
- a) modprobe driver debug=7
- b) In /etc/modprobe.d/driver.conf:
- options driver debug=7
-
- 2) Recreate the problem with the higher debug level,
- send all logs to the maintainer.
-
- 3) Download you card's diagnostic tool from Donald
- Becker's website <http://www.scyld.com/ethercard_diag.html>.
- Download mii-diag.c as well. Build these.
-
- a) Run 'vortex-diag -aaee' and 'mii-diag -v' when the card is
- working correctly. Save the output.
-
- b) Run the above commands when the card is malfunctioning. Send
- both sets of output.
-
-Finally, please be patient and be prepared to do some work. You may
-end up working on this problem for a week or more as the maintainer
-asks more questions, asks for more tests, asks for patches to be
-applied, etc. At the end of it all, the problem may even remain
-unresolved.

- Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the 3Com FastEtherLink and FastEtherLink
-XL, 3Com's PCI to 10/100baseT adapters. It also works with the 10Mbs
-versions of the FastEtherLink cards. The supported product IDs are
- 3c590, 3c592, 3c595, 3c597, 3c900, 3c905
-
-The related ISA 3c515 is supported with a separate driver, 3c515.c, included
-with the kernel source or available from
- cesdis.gsfc.nasa.gov:/pub/linux/drivers/3c515.html
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board. The system BIOS should be set to assign the
-PCI INTA signal to an otherwise unused system IRQ line.
-
-The EEPROM settings for media type and forced-full-duplex are observed.
-The EEPROM media type should be left at the default "autoselect" unless using
-10base2 or AUI connections which cannot be reliably detected.
-
-III. Driver operation
-
-The 3c59x series use an interface that's very similar to the previous 3c5x9
-series. The primary interface is two programmed-I/O FIFOs, with an
-alternate single-contiguous-region bus-master transfer (see next).
-
-The 3c900 "Boomerang" series uses a full-bus-master interface with separate
-lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
-DEC Tulip and Intel Speedo3. The first chip version retains a compatible
-programmed-I/O interface that has been removed in 'B' and subsequent board
-revisions.
-
-One extension that is advertised in a very large font is that the adapters
-are capable of being bus masters. On the Vortex chip this capability was
-only for a single contiguous region making it far less useful than the full
-bus master capability. There is a significant performance impact of taking
-an extra interrupt or polling for the completion of each transfer, as well
-as difficulty sharing the single transfer engine between the transmit and
-receive threads. Using DMA transfers is a win only with large blocks or
-with the flawed versions of the Intel Orion motherboard PCI controller.
-
-The Boomerang chip's full-bus-master interface is useful, and has the
-currently-unused advantages over other similar chips that queued transmit
-packets may be reordered and receive buffer groups are associated with a
-single frame.
-
-With full-bus-master support, this driver uses a "RX_COPYBREAK" scheme.
-Rather than a fixed intermediate receive buffer, this scheme allocates
-full-sized skbuffs as receive buffers. The value RX_COPYBREAK is used as
-the copying breakpoint: it is chosen to trade-off the memory wasted by
-passing the full-sized skbuff to the queue layer for all frames vs. the
-copying cost of copying a frame to a correctly-sized skbuff.
-
-IIIC. Synchronization
-The driver runs as two independent, single-threaded flows of control. One
-is the send-packet routine, which enforces single-threaded use by the
-dev->tbusy flag. The other thread is the interrupt handler, which is single
-threaded by the hardware and other software.
-
-IV. Notes
-
-Thanks to Cameron Spitzer and Terry Murphy of 3Com for providing development
-3c590, 3c595, and 3c900 boards.
-The name "Vortex" is the internal 3Com project name for the PCI ASIC, and
-the EISA version is called "Demon". According to Terry these names come
-from rides at the local amusement park.
-
-The new chips support both ethernet (1.5K) and FDDI (4.5K) packet sizes!
-This driver only supports ethernet packets because of the skbuff allocation
-limit of 4K.

These drivers use the 7990 core with wrappers for the HP300 and
Motorola MVME147 SBC circa 1998. It is unlikely they are used with a
modern kernel.

I have an MVME147 blinking away running mainline using the mvme147 driver.
I think some of these need to be CC'd to the specific arch lists so
the few people using them get a chance to pipe up.
I think I'm the last person to have touched the mvme147, I don't mind
being a maintainer for it.
Cheers,
Daniel

That is part of the problem. No MAINTAINERs entry. so
./scripts/get_maintainers.py does not add an Cc: to the list.

Please submit an entry for MAINTAINERs.
I will drop this patch.

The lance was written by Donald Becker between 1993-1998. It is an ISA
device, so unlikely to be used with modern kernels.

- Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the AMD 79C960, the "PCnet-ISA
-single-chip ethernet controller for ISA". This chip is used in a wide
-variety of boards from vendors such as Allied Telesis, HP, Kingston,
-and Boca. This driver is also intended to work with older AMD 7990
-designs, such as the NE1500 and NE2100, and newer 79C961. For convenience,
-I use the name LANCE to refer to all of the AMD chips, even though it properly
-refers only to the original 7990.
-
-II. Board-specific settings
-
-The driver is designed to work the boards that use the faster
-bus-master mode, rather than in shared memory mode. (Only older designs
-have on-board buffer memory needed to support the slower shared memory mode.)
-
-Most ISA boards have jumpered settings for the I/O base, IRQ line, and DMA
-channel. This driver probes the likely base addresses:
-{0x300, 0x320, 0x340, 0x360}.
-After the board is found it generates a DMA-timeout interrupt and uses
-autoIRQ to find the IRQ line. The DMA channel can be set with the low bits
-of the otherwise-unused dev->mem_start value (aka PARAM1). If unset it is
-probed for by enabling each free DMA channel in turn and checking if
-initialization succeeds.
-
-The HP-J2405A board is an exception: with this board it is easy to read the
-EEPROM-set values for the base, IRQ, and DMA. (Of course you must already
-_know_ the base address -- that field is for writing the EEPROM.)
-
-III. Driver operation
-
-IIIa. Ring buffers
-The LANCE uses ring buffers of Tx and Rx descriptors. Each entry describes
-the base and length of the data buffer, along with status bits. The length
-of these buffers is set by LANCE_LOG_{RX,TX}_BUFFERS, which is log_2() of
-the buffer length (rather than being directly the buffer length) for
-implementation ease. The current values are 2 (Tx) and 4 (Rx), which leads to
-ring sizes of 4 (Tx) and 16 (Rx). Increasing the number of ring entries
-needlessly uses extra space and reduces the chance that an upper layer will
-be able to reorder queued Tx packets based on priority. Decreasing the number
-of entries makes it more difficult to achieve back-to-back packet transmission
-and increases the chance that Rx ring will overflow. (Consider the worst case
-of receiving back-to-back minimum-sized packets.)
-
-The LANCE has the capability to "chain" both Rx and Tx buffers, but this driver
-statically allocates full-sized (slightly oversized -- PKT_BUF_SZ) buffers to
-avoid the administrative overhead. For the Rx side this avoids dynamically
-allocating full-sized buffers "just in case", at the expense of a
-memory-to-memory data copy for each packet received. For most systems this
-is a good tradeoff: the Rx buffer will always be in low memory, the copy
-is inexpensive, and it primes the cache for later packet processing. For Tx
-the buffers are only used when needed as low-memory bounce buffers.
-
-IIIB. 16M memory limitations.
-For the ISA bus master mode all structures used directly by the LANCE,
-the initialization block, Rx and Tx rings, and data buffers, must be
-accessible from the ISA bus, i.e. in the lower 16M of real memory.
-This is a problem for current Linux kernels on >16M machines. The network
-devices are initialized after memory initialization, and the kernel doles out
-memory from the top of memory downward. The current solution is to have a
-special network initialization routine that's called before memory
-initialization; this will eventually be generalized for all network devices.
-As mentioned before, low-memory "bounce-buffers" are used when needed.
-
-IIIC. Synchronization
-The driver runs as two independent, single-threaded flows of control. One
-is the send-packet routine, which enforces single-threaded use by the
-dev->tbusy flag. The other thread is the interrupt handler, which is single
-threaded by the hardware and other software.
-
-The send packet thread has partial control over the Tx ring and 'dev->tbusy'
-flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next
-queue slot is empty, it clears the tbusy flag when finished otherwise it sets
-the 'lp->tx_full' flag.
-
-The interrupt handler has exclusive control over the Rx ring and records stats
-from the Tx ring. (The Tx-done interrupt can't be selectively turned off, so
-we can't avoid the interrupt overhead by having the Tx routine reap the Tx
-stats.) After reaping the stats, it marks the queue entry as empty by setting
-the 'base' to zero. Iff the 'lp->tx_full' flag is set, it clears both the
-tx_full and tbusy flags.
-
-*/
-
-/* Set the number of Tx and Rx buffers, using Log_2(# buffers).
- Reasonable default values are 16 Tx buffers, and 16 Rx buffers.
- That translates to 4 and 4 (16 == 2^^4).
- This is a compile-time option for efficiency.

The nmclan was written by Roger C Pao in 1995. It is an PCMCIA device,
so unlikely to be used with modern kernels.

-Linux PCMCIA ethernet adapter driver for the New Media Ethernet LAN.
- nmclan_cs.c,v 0.16 1995/07/01 06:42:17 rpao Exp rpao
-
- The Ethernet LAN uses the Advanced Micro Devices (AMD) Am79C940 Media
- Access Controller for Ethernet (MACE). It is essentially the Am2150
- PCMCIA Ethernet card contained in the Am2150 Demo Kit.

-Driver Notes and Issues
--------------------------------------------------------------------------------
-
-1. Developed on a Dell 320SLi
- PCMCIA Card Services 2.6.2
- Linux dell 1.2.10 #1 Thu Jun 29 20:23:41 PDT 1995 i386
-
-2. rc.pcmcia may require loading pcmcia_core with io_speed=300:
- 'insmod pcmcia_core.o io_speed=300'.
- This will avoid problems with fast systems which causes rx_framecnt
- to return random values.
-
-3. If hot extraction does not work for you, use 'ifconfig eth0 down'
- before extraction.
-
-4. There is a bad slow-down problem in this driver.
-
-5. Future: Multicast processing. In the meantime, do _not_ compile your
- kernel with multicast ip enabled.

- * 2.5.75-ac1 2003/07/11 Alan Cox <alan@lxorguk.ukuu.org.uk>
- * Fixed hang on card eject as we probe it
- * Cleaned up to use new style locking.
- *
- * Revision 0.16 1995/07/01 06:42:17 rpao
- * Bug fix: nmclan_reset() called CardServices incorrectly.
- *
- * Revision 0.15 1995/05/24 08:09:47 rpao
- * Re-implement MULTI_TX dev->tbusy handling.
- *
- * Revision 0.14 1995/05/23 03:19:30 rpao
- * Added, in nmclan_config(), "tuple.Attributes = 0;".
- * Modified MACE ID check to ignore chip revision level.
- * Avoid tx_free_frames race condition between _start_xmit and _interrupt.
- *
- * Revision 0.13 1995/05/18 05:56:34 rpao
- * Statistics changes.
- * Bug fix: nmclan_reset did not enable TX and RX: call restore_multicast_list.
- * Bug fix: mace_interrupt checks ~MACE_IMR_DEFAULT. Fixes driver lockup.
- *
- * Revision 0.12 1995/05/14 00:12:23 rpao
- * Statistics overhaul.

The smc91c92 was written by David A Hinds in 1999. It is an PCMCIA
device, so unlikely to be used with modern kernels.

- A PCMCIA ethernet driver for SMC91c92-based cards.

- multifunction cards.

- smc91c92_cs.c 1.122 2002/10/25 06:26:39
-
- This driver contains code written by Donald Becker
- (becker@scyld.com), Rowan Hughes (x-csrdh@jcu.edu.au),
- David Hinds (dahinds@users.sourceforge.net), and Erik Stahlman
- (erik@vt.edu). Donald wrote the SMC 91c92 code using parts of
- Erik's SMC 91c94 driver. Rowan wrote a similar driver, and I've
- incorporated some parts of his driver here. I (Dave) wrote most
- of the PCMCIA glue code, and the Ositech support code. Kelly
- Stephens (kstephen@holli.com) added support for the Motorola
- Mariner, with help from Allen Brost.

-
- Changelog:
-
- Mike Cruse : mcruse@cti-ltd.com
- : Changes for Linux 2.0 compatibility.
- : Added dev_id parameter in net_interrupt(),
- : request_irq() and free_irq(). Just NULL for now.
-
- Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
- : in net_open() and net_close() so kerneld would know
- : that the module is in use and wouldn't eject the
- : driver prematurely.
-
- Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c
- : as an example. Disabled autoprobing in init_module(),
- : not a good thing to do to other devices while Linux
- : is running from all accounts.
-
- Alan Cox : Removed 1.2 support, added 2.1 extra counters.
-
- David Huggins-Daines <dhd@debian.org>
-
- Split this off into mac89x0.c, and gutted it of all parts which are
- not relevant to the existing CS8900 cards on the Macintosh
- (i.e. basically the Daynaport CS and LC cards). To be precise:
-
- * Removed all the media-detection stuff, because these cards are
- TP-only.
-
- * Lobotomized the ISA interrupt bogosity, because these cards use
- a hardwired NuBus interrupt and a magic ISAIRQ value in the card.
-
- * Basically eliminated everything not relevant to getting the
- cards minimally functioning on the Macintosh.
-
- I might add that these cards are badly designed even from the Mac
- standpoint, in that Dayna, in their infinite wisdom, used NuBus slot
- I/O space and NuBus interrupts for these cards, but neglected to
- provide anything even remotely resembling a NuBus ROM. Therefore we
- have to probe for them in a brain-damaged ISA-like fashion.
-
- Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 11/01/2001
- check kmalloc and release the allocated memory on failure in
- mac89x0_probe and in init_module
- use local_irq_{save,restore}(flags) in net_get_stat, not just
- local_irq_{dis,en}able()

I think I might be using this with a mac and I'm running mainline.
FWIW the m68k mac stuff still works perfectly fine with modern kernels
and there are people using it.

> - Changelog:
> -
> - Mike Cruse : mcruse@cti-ltd.com
> - : Changes for Linux 2.0 compatibility.
> - : Added dev_id parameter in net_interrupt(),
> - : request_irq() and free_irq(). Just NULL for now.
> -
> - Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
> - : in net_open() and net_close() so kerneld would know
> - : that the module is in use and wouldn't eject the
> - : driver prematurely.
> -
> - Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c
> - : as an example. Disabled autoprobing in init_module(),
> - : not a good thing to do to other devices while Linux
> - : is running from all accounts.
> -
> - Alan Cox : Removed 1.2 support, added 2.1 extra counters.
> -
> - David Huggins-Daines <dhd@debian.org>
> -
> - Split this off into mac89x0.c, and gutted it of all parts which are
> - not relevant to the existing CS8900 cards on the Macintosh
> - (i.e. basically the Daynaport CS and LC cards). To be precise:
> -
> - * Removed all the media-detection stuff, because these cards are
> - TP-only.
> -
> - * Lobotomized the ISA interrupt bogosity, because these cards use
> - a hardwired NuBus interrupt and a magic ISAIRQ value in the card.
> -
> - * Basically eliminated everything not relevant to getting the
> - cards minimally functioning on the Macintosh.
> -
> - I might add that these cards are badly designed even from the Mac
> - standpoint, in that Dayna, in their infinite wisdom, used NuBus slot
> - I/O space and NuBus interrupts for these cards, but neglected to
> - provide anything even remotely resembling a NuBus ROM. Therefore we
> - have to probe for them in a brain-damaged ISA-like fashion.
> -
> - Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 11/01/2001
> - check kmalloc and release the allocated memory on failure in
> - mac89x0_probe and in init_module
> - use local_irq_{save,restore}(flags) in net_get_stat, not just
> - local_irq_{dis,en}able()

The fmvj18x was written by Shingo Fujimoto in 2002. It is an PCMCIA
device, so unlikely to be used with modern kernels.

- The PCMCIA client code is based on code written by David Hinds.
- Network code is based on the "FMV-18x driver" by Yutaka TAMIYA

The xirc2ps was written by Werner Koch in 1997. It is an PCMCIA
device, so unlikely to be used with modern kernels.

- * Xircom CreditCard Ethernet Adapter IIps driver
- * Xircom Realport 10/100 (RE-100) driver
- *
- * This driver supports various Xircom CreditCard Ethernet adapters
- * including the CE2, CE IIps, RE-10, CEM28, CEM33, CE33, CEM56,
- * CE3-100, CE3B, RE-100, REM10BT, and REM56G-100.
- *
- * 2000-09-24 <psheer@icon.co.za> The Xircom CE3B-100 may not
- * autodetect the media properly. In this case use the
- * if_port=1 (for 10BaseT) or if_port=4 (for 100BaseT) options
- * to force the media type.
- *
- * Written originally by Werner Koch based on David Hinds' skeleton of the

The ax88190 was written by David A. Hindsh in 2001. It is an PCMCIA
device, so unlikely to be used with modern kernels.

- A PCMCIA ethernet driver for Asix AX88190-based cards
-
- The Asix AX88190 is a NS8390-derived chipset with a few nasty
- idiosyncracies that make it very inconvenient to support with a
- standard 8390 driver. This driver is based on pcnet_cs, with the
- tweaked 8390 code grafted on the end. Much of what I did was to
- clean up and update a similar driver supplied by Asix, which was
- adapted by William Lee, william@asix.com.tw.

- This is the chip-specific code for many 8390-based ethernet adaptors.
- This is not a complete driver, it must be combined with board-specific
- code such as ne.c, wd.c, 3c503.c, etc.
-
- Seeing how at least eight drivers use this code, (not counting the
- PCMCIA ones either) it is easy to break some card by what seems like
- a simple innocent change. Please contact me or Donald if you think
- you have found something that needs changing. -- PG
-
- Changelog:
-
- Paul Gortmaker : remove set_bit lock, other cleanups.
- Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
- ei_block_input() for eth_io_copy_and_sum().
- Paul Gortmaker : exchange static int ei_pingpong for a #define,
- also add better Tx error handling.
- Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
- Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
- Paul Gortmaker : tweak ANK's above multicast changes a bit.
- Paul Gortmaker : update packet statistics for v2.1.x
- Alan Cox : support arbitrary stupid port mappings on the
- 68K Macintosh. Support >16bit I/O spaces
- Paul Gortmaker : add kmod support for auto-loading of the 8390
- module by all drivers that require it.
- Alan Cox : Spinlocking work, added 'BUG_83C690'
- Paul Gortmaker : Separate out Tx timeout code from Tx path.

- * SMP and the 8390 setup.
- *
- * The 8390 isn't exactly designed to be multithreaded on RX/TX. There is
- * a page register that controls bank and packet buffer access. We guard
- * this with ei_local->page_lock. Nobody should assume or set the page other
- * than zero when the lock is not held. Lock holders must restore page 0
- * before unlocking. Even pure readers must take the lock to protect in
- * page 0.
- *
- * To make life difficult the chip can also be very slow. We therefore can't
- * just use spinlocks. For the longer lockups we disable the irq the device
- * sits on and hold the lock. We must hold the lock because there is a dual
- * processor case other than interrupts (get stats/set multicast list in
- * parallel with each other and transmit).
- *
- * Note: in theory we can just disable the irq on the card _but_ there is
- * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
- * enter lock, take the queued irq. So we waddle instead of flying.
- *
- * Finally by special arrangement for the purpose of being generally
- * annoying the transmit function is called bh atomic. That places
- * restrictions on the user context callers as disable_irq won't save
- * them.

The pcnet was written by David A. Hindsh in 1999. It is an PCMCIA
device, so unlikely to be used with modern kernels.

- A PCMCIA ethernet driver for NS8390-based cards
-
- This driver supports the D-Link DE-650 and Linksys EthernetCard
- cards, the newer D-Link and Linksys combo cards, Accton EN2212
- cards, the RPTI EP400, and the PreMax PE-200 in non-shared-memory
- mode, and the IBM Credit Card Adapter, the NE4100, the Thomas
- Conrad ethernet card, and the Kingston KNE-PCM/x in shared-memory
- mode. It will also handle the Socket EA card in either mode.

- Important: There have been many reports that, with some motherboards
- mixing an SMC Ultra and an Adaptec AHA154x SCSI card (or compatible,
- such as some BusLogic models) causes corruption problems with many
- operating systems. The Linux smc-ultra driver has a work-around for
- this but keep it in mind if you have such a SCSI card and have
- problems.
-
- To compile this driver as a module, choose M here. The module
- will be called smc-ultra.

-/* smc-ultra.c: A SMC Ultra ethernet driver for linux. */
-/*
- This is a driver for the SMC Ultra and SMC EtherEZ ISA ethercards.
-
- Written 1993-1998 by Donald Becker.

-
- This driver uses the cards in the 8390-compatible mode.
- Most of the run-time complexity is handled by the generic code in
- 8390.c. The code in this file is responsible for
-
- ultra_probe() Detecting and initializing the card.
- ultra_probe1()
- ultra_probe_isapnp()
-
- ultra_open() The card-specific details of starting, stopping
- ultra_reset_8390() and resetting the 8390 NIC core.
- ultra_close()
-
- ultra_block_input() Routines for reading and writing blocks of
- ultra_block_output() packet buffer memory.
- ultra_pio_input()
- ultra_pio_output()
-
- This driver enables the shared memory only when doing the actual data
- transfers to avoid a bug in early version of the card that corrupted
- data transferred by a AHA1542.
-
- This driver now supports the programmed-I/O (PIO) data transfer mode of
- the EtherEZ. It does not use the non-8390-compatible "Altego" mode.
- That support (if available) is in smc-ez.c.
-
- Changelog:
-
- Paul Gortmaker : multiple card support for module users.
- Donald Becker : 4/17/96 PIO support, minor potential problems avoided.
- Donald Becker : 6/6/96 correctly set auto-wrap bit.
- Alexander Sotirov : 1/20/01 Added support for ISAPnP cards
-
- Note about the ISA PnP support:
-
- This driver can not autoprobe for more than one SMC EtherEZ PnP card.
- You have to configure the second card manually through the /proc/isapnp
- interface and then load the module with an explicit io=0x___ option.

There should be 18 patches in this series, but it seems like b4 send

I maybe have a fix, but i will wait the usual 24 hours before
retrying.

You should be able to tell from this what is missing, and i would like

Looks like they ended up coming thru and got nom-nomed by the AIs,
which flagged some omissions (in docs mostly). So I'll keep the series
as "changes requested".
Please feel free to ignore the 24h limit for this. We need the
deletions shipped to Linus by Thu.

Hi Andrew,
I happen to still use this driver on several hundred industrial PC
installations that were outfitted with 3com 3C905-B & CX cards 15+ years ago.
The old hardware still runs, therefore those cards haven't needed to be
replaced. I keep these systems up to date with the latest Linux kernel roughly
once per year.
I understand the maintenance burden, but I would be delighted to continue
receiving bug fixes for this driver via the mainline Linux kernel if you are
still willing to continue to support it.
Thanks and best regards,
-Byron

Looking at the history of 3c59x.c i see:
Date: Tue Jan 6 10:47:21 2026 +0100
net: 3com: 3c59x: fix possible null dereference in vortex_probe1()

3c59x: balance page maps and unmaps
Date: Tue Jul 7 20:48:55 2015 +0200
3c59x: Fix shared IRQ handling
So it looks like it was been pretty stable since 2016.
Could you live with v6.18, which has an expected EOL of December 2028?
If you are only updating once per year, security is not an issue, you
just want stability.
In fact, you might actually find stability starts going down in the
next couple of years, maybe sooner. What we expect to happen soon is a
lot more AI generated 'bug fixes', probably from newbies who are
unable to evaluate if the AI is generated good fixes or bad fixes, or
fixes which are theoretical rather than actual bugs etc. We netdev
Maintainers are already seeing the number of patches going up, and are
expecting to get overloaded. Which means quality will go down. We have
also seen the AI generated fixes are indiscriminate, neither the AI,
nor the human, care, or even look, to see if the driver is from the
last century. We Maintainers however would prefer spending our time on
drivers from the last ten years, maybe newer. So patches for these
older drivers is going to get less review, and bad patches will slip
through.
By dropping them for the current HEAD, we are reducing our surface
area. It will be interesting to see if the AI patches are only for
HEAD, or they start going back to older kernels to find 'bugs'.
However, just because a driver has gone from HEAD, it does not really
prevent us from taking patches for stable. But we Maintainers want to
avoid doing the triage work, figuring out good from bad.
We have not discussed it as a Maintainer team, but one thing which
might work is we add a entry for 3c59x.c in MAINTAINERS, in stable,
pointing to you. You can then validate patches, and tell us if they
are O.K. to queue for stable.

I could for the time being, but this hasn't worked for me in the past. Usually
what happens is the PC breaks down, and the customer swaps in a new
backplane+SBC and moves all their PCI cards over. I then find I need to update
the kernel just to get the Intel DRM to work properly on the new CPU. Some of
these systems were installed back in the Linux 2.6 era, so I've gone through
several "Intel DRM not working" steps ever since CPUs started getting
integrated graphics. 2028 will come fast.
One thing worth mentioning though--these 3com cards are all PCI. They still
work perfectly fine on the newest hardware. Your subject says you're dropping
old ISA and PCMCIA support, so I don't fully understand why you included 3c59x
in the mix. Phoronix picked up this patch
(https://www.phoronix.com/news/Linux-Old-Network-AI), and according to the
comments, there are still people who use these cards (3c905s were very popular
back in the day). Would you be willing to leave this driver in mainline?

I'm sorry, but I already have enough going on to take up another maintainer
role. However, I thought Greg had some rule in place that said the stable
branches don't get any patches applied unless they also hit mainline. Is there
some exception for drivers in stable that don't exist in mainline anymore?
Thanks,

I replied to the single patches for the ones I think I have off the
top of my head but maybe I have a few other these.
I think on x86 people running machines that have real ISA slots and a
modern kernel are going to be fairly rare but I think there is non-x86
hardware that has some of these and people are still using them.
I think the pcnet one is used in some PC emulators too?
This is just my opinion but I think it'd be good to give people a bit
more time before they get removed. I thought I was the only person
using the 68000 (a cpu from 1979) code in the m68k tree for years
until out of the blue a month or so ago someone popped up and asked if
I could fix a bug in it since I'd fixed a different bug in it
recently.
Maybe we could add a special thing in the maintainers for "this is
code only crazy people use" and have a rule to ignore untested AI
generated patches for it? :)
Thanks,
Daniel

Is marking them EXPERT or BROKEN enough?
(Or a similar new option.)

I think EXPERT gives the wrong impression that they are difficult to
use and BROKEN makes it seem like they don't work.
NEEDSHOBBIES or LIVINGINTHEPAST ?
Seriously though, I think we should have something to mark stuff in

They might still be used for retro-computing on various non-x86 computers
such as Alphas, older SPARC systems, PA-RISC and 68000 systems. Please don't
assume that every computer is just an x86 computer.
As for the AI-generated bug reports, I assume this will settle down sooner
or later when reporters realize not every issue is being addressed. Anyone
who is still using this old hardware won't be using them on machines directly
connected to the internet.
So, why bother? Just ignore those bug reports.
Adrian

Thanks for your series!

Only the drivers that depend solely on ISA or PCMCIA are drivers
for ISA and PCMCIA devices.
These are not:
- depends on (PCI || EISA) && HAS_IOPORT_MAP
- depends on DIO
- depends on MVME147
- depends on ARM || (COMPILE_TEST && !PPC)
- depends on MAC

They are not much of a maintenance burden because they are small, mature
and stable.

AI helps find issues but AI also helps resolve issues.

Removing these old drivers makes little sense, if the issues were only
noticed by AI and not by actual users.
