Subject: [PATCH v1 net-next 0/6] net: napi: add CPU affinity to napi->config

Move the IRQ affinity management to the napi struct. All drivers that are
already using netif_napi_set_irq() are modified to the new API. Except
mlx5 because it is implementing IRQ pools and moving to the new API does
not seem trivial.

Tested on bnxt, ice and idpf.
---
Opens: is cpu_online_mask the best default mask? drivers do this differently 

RFC -> v1:
    - move static inline affinity functions to net/dev/core.c
    - add the new napi->irq_flags (patch 1)
    - add code changes to bnxt, mlx4 and ice.

Ahmed Zaki (6):
  net: napi: add irq_flags to napi struct
  net: napi: add CPU affinity to napi->config
  bnxt: use napi's irq affinity
  mlx4: use napi's irq affinity
  ice: use napi's irq affinity
  idpf: use napi's irq affinity
