Subject: [git patches] net driver fixes
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:
