Subject: [git patches] net driver fixes

From: Jeff Garzik <[email-masked]>
Date: Wed, 20 Feb 2008 11:55:57 -0500

Note:  this is based off of Linus's latest commit
(5d9c4a7de64d398604a978d267a6987f1f4025b7), since all my previous
submissions are now upstream (thanks!).

Please pull from 'upstream-davem' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git upstream-davem

to receive the following updates:
