Subject: [git patches] net driver updates
Nothing highly notable. Wireless pull, and new blackfin eth driver
(didn't get merged with rest of blackfin, since additional review was
requested).
Please pull from 'upstream-linus' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git upstream-linus
to receive the following updates:
