Hi,

Oops. I forgot the patch.

Peter.

+
+ Changelog:
+
+ Mike Cruse : mcruse@cti-ltd.com
+ : Changes for Linux 2.0 compatibility.
+ : Added dev_id parameter in net_interrupt(),
+ : request_irq() and free_irq(). Just NULL for now.
+
+ Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
+ : in net_open() and net_close() so kerneld would know
+ : that the module is in use and wouldn't eject the
+ : driver prematurely.
+
+ Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c
+ : as an example. Disabled autoprobing in init_module(),
+ : not a good thing to do to other devices while Linux
+ : is running from all accounts.
+
+ Russ Nelson : Jul 13 1998. Added RxOnly DMA support.
+
+ Melody Lee : Aug 10 1999. Changes for Linux 2.2.5 compatibility.
+ : email: ethernet@crystal.cirrus.com
+
+ Alan Cox : Removed 1.2 support, added 2.1 extra counters.
+
+ Andrew Morton : andrewm@uow.edu.au
+ : Kernel 2.3.48
+ : Handle kmalloc() failures
+ : Other resource allocation fixes
+ : Add SMP locks
+ : Integrate Russ Nelson's ALLOW_DMA functionality back in.
+ : If ALLOW_DMA is true, make DMA runtime selectable
+ : Folded in changes from Cirrus (Melody Lee
+ : <klee@crystal.cirrus.com>)
+ : Don't call netif_wake_queue() in net_send_packet()
+ : Fixed an out-of-mem bug in dma_rx()
+ : Updated Documentation/cs89x0.txt
+
+ Andrew Morton : andrewm@uow.edu.au / Kernel 2.3.99-pre1
+ : Use skb_reserve to longword align IP header (two places)
+ : Remove a delay loop from dma_rx()
+ : Replace '100' with HZ
+ : Clean up a couple of skb API abuses
+ : Added 'cs89x0_dma=N' kernel boot option
+ : Correctly initialise lp->lock in non-module compile
+
+ Andrew Morton : andrewm@uow.edu.au / Kernel 2.3.99-pre4-1
+ : MOD_INC/DEC race fix (see
+ : http://www.uwsg.indiana.edu/hypermail/linux/kernel/0003.3/1532.html)
+
+ Peter De Schrijver: p2@mind.be
+ : changes to support PCMCIA
