v2: - we can't remove the left part of TSO settings to lib vhost, which
      hurts VM2VM performance badly.

Ksiadz reported that TSO won't work for OVS with NIC, even with those
similar changes from the commit 9fd72e3cbd29 ("examples/vhost: add
virtio offload").

This gives me another chance to look at the TSO implementation a bit
deeper, and then came up with this small patch set, which includes a
TSO cleanup and fix.

Patch 4 is a vlan tag fix reported from Qian.

Applied, thanks
