2.4.0 Patch for 3c575

Aaron Eppert
2001-01-11T01:42:54Z

Attached is a patch against 2.4.0 to add the 3c575 driver
into the kernel. Simple reasoning for the addition involves
the rather broad use of this card and the need to have it
in a standard kernel.

+ 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
+in the pci_tbl[] list.
+
+The related ISA 3c515 is supported with a separate driver, 3c515.c, included
+with the kernel source.
+
+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 by the tx queue
+system. 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 on some kernels because of the
+skbuff allocation limit of 4K.
