Right I'm not suggesting having this as a default.  However,
if you have a finely tuned system (e.g., a router) where you've
pinned all you RX queues to specific CPUs and your local apps
as well then it would make sense to provide this as an alternative.

If this alternative doesn't exist, then unless the RX hash happens
to match the TX hash, for routing at least the packets are going
to jump all over the place which isn't nice.

Cheers,
