Adding yet another layer and cache misses.

This might be a win for stress situations, not for nominal traffic,
when very few packets are delivered per NAPI poll.

For stress situations, we do not rely on RPS/RFS at all, but prefer RSS

For the router case, where Jesper wants 15 Mpps on a single core,
RPS/RFS is not used.
