Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

The UDP offload conflict is dealt with by simply taking what is
in net-next where we have removed all of the UFO handling code
entirely.

The TCP conflict was a case of local variables in a function
being removed from both net and net-next.

In netvsc we had an assignment right next to where a missing
set of u64 stats sync object inits were added.
