1 | /* smc-mca.c: A SMC Ultra ethernet driver for linux. */ |
2 | /* | |
3 | 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.) | |
20 | ||
21 | 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 | |
