stmmac: add VLAN priority based RX steering
The current tc flower implementation in stmmac supports both L3 and L4
filter offloading. This patch adds the support of VLAN priority based
RX frame steering into different Rx Queues.
The patches have been tested on both configuration test (include L3/L4)
and traffic test (multi VLAN ping streams with RX Frame Steering) below:-
