In order to release PnP resources a card type must be set to EL3_PNP. Previously, it was never set hence the PnP resources were not released and device was left in incorrect state. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: Jeff Garzik <jeff@garzik.org>

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