net: Add GSO to vlan_features initialization
Just add GSO to vlan_features initialization, and update comments. When we set offload features, vlan_dev_fix_features() will do more check. In vlan_dev_fix_features(), final features is decided by features of real device and vlan_features of real device. Signed-off-by: Shan Wei <shanwei@cn.fujitsu.com> Signed-off-by: David S.
