/* smc-mca.c: A SMC Ultra ethernet driver for linux. */
|

|
|
/*

|
|
Most of this driver, except for ultramca_probe is nearly
|
4 |
|
|
verbatim from smc-ultra.c by Donald Becker. The rest is
|
5 |
|
|
written and copyright 1996 by David Weis, weisd3458@uni.edu
|
6 |
|
|
|
7 |
|
|
This is a driver for the SMC Ultra and SMC EtherEZ ethercards.
|
8 |
|
|
|
9 |
|
|
This driver uses the cards in the 8390-compatible, shared memory mode.
|
10 |
|
|
Most of the run-time complexity is handled by the generic code in
|
11 |
|
|
8390.c.
|
12 |
|
|
|
13 |
|
|
This driver enables the shared memory only when doing the actual data
|
14 |
|
|
transfers to avoid a bug in early version of the card that corrupted
|
15 |
|
|
data transferred by a AHA1542.
|
16 |
|
|
|
17 |
|
|
This driver does not support the programmed-I/O data transfer mode of
|
18 |
|
|
the EtherEZ. That support (if available) is smc-ez.c. Nor does it
|
19 |
|
|
use the non-8390-compatible "Altego" mode. (No support currently planned.)

Changelog:
|
22 |
|
|
|
23 |
|
|
Paul Gortmaker : multiple card support for module users.
|
24 |
|
|
David Weis : Micro Channel-ized it.
|
25 |
|
|
Tom Sightler : Added support for IBM PS/2 Ethernet Adapter/A
|
26 |
|
|
Christopher Turcksin : Changed MCA-probe so that multiple adapters are
|
27 |
|
|
found correctly (Jul 16, 1997)
|
28 |
|
|
Chris Beauregard : Tried to merge the two changes above (Dec 15, 1997)
|
29 |
|
|
Tom Sightler : Fixed minor detection bug caused by above merge
|
30 |
|
|
Tom Sightler : Added support for three more Western Digital
|
31 |
|
|
MCA-adapters
|
32 |
|
|
Tom Sightler : Added support for 2.2.x mca_find_unused_adapter
|
33 |
|
|
Hartmut Schmidt : - Modified parameter detection to handle each
|
34 |
|
|
card differently depending on a switch-list
|
35 |
|
|
- 'card_ver' removed from the adapter list
|
36 |
|
|
- Some minor bug fixes
