Link IRQs to NAPI instances with netif_napi_set_irq. This
information can be queried with the netdev-genl API.

Also add support for persistent NAPI configuration using
netif_napi_add_config().

Did you test the persistent NAPI config on one of these devices?

Hi Joe,

Yes, I tested it, and the persistent NAPI config worked correctly on
the device.

Thanks,
