Subject: [net-next PATCH 0/2] vlan TSO support for virtio-net

This series simply enable the vlan TSO support for virtio-net by just initialize
vlan_features for virtio-net and tun which allows vlan TSO packets to be
processed in both TX and RX path for virtio-net.

Netperf shows great improvements on stream tests:

Guest sending:   4162.35 10^6bits/sec
Guest receiving: 2786.67 10^6bit/sec

After:
Guest sending:   9365.42 10^6bits/sec
Guest receiving: 8085.49 10^6bit/sec
