Subject: [git patches] net driver fixes
Note that this is a completely separate branch from 'netxen-ioctl',
submitted separately. Each can be pulled (or not) independently. I
mention this mainly because this submit also includes [non-conflicting]
NetXen changes.
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:
