Subject: [net-next v6 9/9] mlx4: Add support for persistent NAPI config to RX CQs

Use netif_napi_add_config to assign persistent per-NAPI config when
initializing RX CQ NAPIs.

Presently, struct napi_config only has support for two fields used for
RX, so there is no need to support them with TX CQs, yet.
