net: stmmac: add RX frame steering based on VLAN priority in tc flower
We extend tc flower to support configuration of VLAN priority-based RX
frame steering hardware offloading.
To map VLAN <PCP> to Traffic Class <TC>:
$ tc filter add dev <IFNAME> parent ffff: protocol 802.1Q flower \
vlan_prio <PCP> hw_tc <TC>
Note: <TC> < N whereby "tc qdisc ... num_tc N ..."
To delete all tc flower configurations:
$ tc qdisc delete dev <IFNAME> ingress
