[PATCH net v2 14/15] drivers: net: 8390: ultra: Remove this driver

Andrew Lunn
2026-04-22T18:28:47Z

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

- select CRC32
- help
- If you have a network (Ethernet) card of this type, say Y here.
-
- 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.

-/*
- This is a driver for the SMC Ultra and SMC EtherEZ ISA ethercards.

-
- 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.
