net/mlx5e: RX, Hook NAPIs to page pools
Linking the NAPI to the rq page_pool to improve page_pool cache
usage during skb recycling.
Here are the observed improvements for a iperf single stream
test case:
- For 1500 MTU and legacy rq, seeing a 20% improvement of cache usage.
- For 9K MTU, seeing 33-40 % page_pool cache usage improvements for
both striding and legacy rq (depending if the application is running on
the same core as the rq or not).
