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.
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.
29 Alan Cox: Removed the 'Unexpected interrupt' bug.
30 Michael Meskes: Upgraded to Donald Becker's version 1.07.
31 Alan Cox: Increased the eeprom delay. Regardless of
32 what the docs say some people definitely
33 get problems with lower (but in card spec)
35 v1.10 4/21/97 Fixed module code so that multiple cards may be detected,
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>
