-/* smc-mca.c: A SMC Ultra ethernet driver for linux. */
-/*
- Most of this driver, except for ultramca_probe is nearly
- verbatim from smc-ultra.c by Donald Becker. The rest is
- written and copyright 1996 by David Weis, weisd3458@uni.edu
-
- This is a driver for the SMC Ultra and SMC EtherEZ ethercards.
-
- This driver uses the cards in the 8390-compatible, shared memory mode.
- Most of the run-time complexity is handled by the generic code in
- 8390.c.
-
- 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 does not support the programmed-I/O data transfer mode of
- the EtherEZ. That support (if available) is smc-ez.c. Nor does it
- use the non-8390-compatible "Altego" mode. (No support currently planned.)
-
- Changelog:
-
- Paul Gortmaker : multiple card support for module users.
- David Weis : Micro Channel-ized it.
- Tom Sightler : Added support for IBM PS/2 Ethernet Adapter/A
- Christopher Turcksin : Changed MCA-probe so that multiple adapters are
- found correctly (Jul 16, 1997)
- Chris Beauregard : Tried to merge the two changes above (Dec 15, 1997)
- Tom Sightler : Fixed minor detection bug caused by above merge
- Tom Sightler : Added support for three more Western Digital
- MCA-adapters
- Tom Sightler : Added support for 2.2.x mca_find_unused_adapter
- Hartmut Schmidt : - Modified parameter detection to handle each
- card differently depending on a switch-list
- - 'card_ver' removed from the adapter list
- - Some minor bug fixes
