Merge branch 'wangxun-netdev-features-support'

Mengyuan Lou says:

====================
Wangxun netdev features support

Implement tx_csum and rx_csum to support hardware checksum offload.
Implement ndo_vlan_rx_add_vid and ndo_vlan_rx_kill_vid.
Implement ndo_set_features.
Enable macros in netdev features which wangxun can support.
====================
