The use case is to spray the packets to multiple queues using RSS on
Tunnel type packets.

Considering the case if RSS hash does not account inner packet in tunnel
case, the packet always to go a particular queue as mostly likely
outer header remains same in tunnel packets and RSS spread
will not be achieved in tunnel packets case.

This feature is part of the RSS capability of ThunderX
NIC HW. Which, we are planning to upstream on next release.

I thought of pushing the common code changes first.
