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
v2:
- Also move the ARFS IRQ affinity management from drivers to core. Via
netif_napi_set_irq(), drivers can ask the core to add the IRQ to the
ARFS rmap (already allocated by the driver).
RFC -> v1:
- https://lore.kernel.org/netdev/20241210002626.366878-1-ah...
- 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 (8):
net: napi: add irq_flags to napi struct
net: allow ARFS rmap management in core
lib: cpu_rmap: allow passing a notifier callback
net: napi: add CPU affinity to napi->config
bnxt: use napi's irq affinity
ice: use napi's irq affinity
idpf: use napi's irq affinity
mlx4: use napi's irq affinity
