Please bring some use cases, thanks. 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. Jerin >
