Subject: [PATCH] ne2k-pci
Date: Wed, 20 Dec 2000 17:00:53 +0100 [thread overview]
Message-ID: <20001220170053.A4716@werewolf.able.es> (raw)
[Sorry if this message is dup. I sent it to the list but did not see it,
so I think this was a problem with my mailer or ISP]
This is a port of the new 1.02 features of the ne2k-pci driver to kernel
2.2.18. Reviewed by Donald Becker, and tested on 2.2.18, 19-pre1 and pre2.
New features:
- module info
- full duplex support in RealTek and Holtek cards. Must be activated
on module load with full_duplex=1, (up to 6 cards).
The patch does not use the pci stuff that D.Becker included in the scyld
drivers ===> Question: is there any similar pci stuff in 2.2.18 and
a driver to look at its use ?
Thanks.ñ
