> Commit bd7c00605ee0 ("net: move aRFS rmap management and CPU affinity to
> core") allows the drivers to delegate the IRQ affinity to the NAPI instance.
> However, the driver needs to use a persistent NAPI config and explicitly set/unset
> the NAPI<->IRQ association.

> Convert to the new IRQ affinity API.
