net: thunderx: Support for HW VLAN stripping
This patch configures HW to strip 802.1Q header if found in a
receiving packet. The stripped VLAN ID and TCI information is
passed on to software via CQE_RX. Also sets netdev's 'vlan_features'
so that other HW offload features can be used for tagged packets.
This offload feature can be enabled or disabled via ethtool.
Network stack normally ignores RPS for 802.1Q packets and hence low
throughput. With this offload enabled throughput for tagged packets
will be almost same as normal packets.
Note: This patch doesn't enable HW VLAN insertion for transmit packets.
