igc: Enable HW VLAN Insertion and HW VLAN Stripping
Add HW VLAN acceleration protocol handling. In case of HW VLAN tagging,
we need that protocol available in the ndo_start_xmit(), so that it will be
stored in a new fields in the skb.
HW offloading is set to OFF by default.
Users are allow to turn on/off Rx/Tx HW VLAN acceleration via ethtool.
