This has a fix to handle small buffer free logic correctly and then

I pushed adjust head at net (even though its rc3) to avoid having
to push another exception case into virtio_net to catch if the
program uses adjust_head and then block it. If there are any strong
objections to this we can push it at net-next and use a patch from
Jakub to add the exception handling but then user space has to deal
with it either via try/fail logic or via kernel version checks. Granted
we already have some cases that need to be configured to enable XDP
but I don't see any reason to have yet another one when we can fix it
now vs delaying a kernel version.


v2: fix spelling error, convert unsigned -> unsigned int
v3: v2 git crashed during send so retrying sorry for the noise
v4: changed layout of rtnl_lock fixes (Stephen)
     moved reset logic into virtio core with new patch (MST)
     fixed up linearize and some code cleanup (Jason)

     Otherwise did some generic code cleanup so might be a bit
     cleaner this time at least that is the hope.

Thanks everyone for the v3 review.

Thanks, looks good to me overall, just few nits.
