Subject: [git patches] net driver updates
Mostly fixes, a few cleanups (generally assisting fixes), and an
exception for PS3 wireless because it had been posted, reviewed and
acked for a while, just not committed.
Please pull from 'upstream-davem' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git upstream-davem
