octeontx2-pf: TC flower offload support for rxqueue mapping 



TC rule support to offload rx queue mapping rules.

Eg:
   tc filter add dev eth2 ingress protocol ip flower \
      dst_ip 192.168.8.100  \
      action skbedit queue_mapping 4 skip_sw
      action mirred ingress redirect dev eth5

Packets destined to 192.168.8.100 will be forwarded to rx
queue 4 of eth5 interface.

   tc filter add dev eth2 ingress protocol ip flower \
      dst_ip 192.168.8.100  \
      action skbedit queue_mapping 9 skip_sw

Packets destined to 192.168.8.100 will be forwarded to rx
queue 4 of eth2 interface.
