18 | Known limitations: | |
19 | Because of the way 3c509 ISA detection works it's difficult to predict | |
20 | a priori which of several ISA-mode cards will be detected first. | |
21 | ||
22 | This driver does not use predictive interrupt mode, resulting in higher | |
23 | packet latency but lower overhead. If interrupts are disabled for an | |
24 | unusually long time it could also result in missed packets, but in | |
25 | practice this rarely happens. | |
26 | ||
27 | ||
28 | FIXES: | |
29 | Alan Cox: Removed the 'Unexpected interrupt' bug. | |
30 | Michael Meskes: Upgraded to Donald Becker's version 1.07. | |
6aa20a22 | 31 | Alan Cox: Increased the eeprom delay. Regardless of |
1da177e4 LT |
32 | what the docs say some people definitely |
33 | get problems with lower (but in card spec) | |
34 | delays | |
35 | v1.10 4/21/97 Fixed module code so that multiple cards may be detected, | |
36 | other cleanups. -djb | |
37 | Andrea Arcangeli: Upgraded to Donald Becker's version 1.12. | |
38 | Rick Payne: Fixed SMP race condition | |
39 | v1.13 9/8/97 Made 'max_interrupt_work' an insmod-settable variable -djb | |
40 | v1.14 10/15/97 Avoided waiting..discard message for fast machines -djb | |
41 | v1.15 1/31/98 Faster recovery for Tx errors. -djb | |
42 | v1.16 2/3/98 Different ID port handling to avoid sound cards. -djb | |
43 | v1.18 12Mar2001 Andrew Morton <andrewm@uow.edu.au> | |
44 | - Avoid bogus detect of 3c590's (Andrzej Krzysztofowicz) | |
45 | - Reviewed against 1.18 from scyld.com | |
46 | v1.18a 17Nov2001 Jeff Garzik <jgarzik@pobox.com> | |
47 | - ethtool support | |
48 | v1.18b 1Mar2002 Zwane Mwaikambo <zwane@commfireservices.com> | |
49 | - Power Management support | |
50 | v1.18c 1Mar2002 David Ruggiero <jdr@farfalle.com> | |
51 | - Full duplex support | |
52 | v1.19 16Oct2002 Zwane Mwaikambo <zwane@linuxpower.ca> | |
53 | - Additional ethtool features | |
54 | v1.19a 28Oct2002 Davud Ruggiero <jdr@farfalle.com> | |
55 | - Increase *read_eeprom udelay to workaround oops with 2 cards. | |
56 | v1.19b 08Nov2002 Marc Zyngier <maz@wild-wind.fr.eu.org> | |
57 | - Introduce driver model for EISA cards. | |
