Subject: rtase: Link IRQs to NAPI instances
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9f611bfd1011797df2ad3461060203a10826e7a4;p=thirdparty%2Flinux.git

rtase: Link IRQs to NAPI instances

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().
