Introduce support for associating napi instances with
corresponding RX and TX queue set. Add the capability
to export napi information supported by the device.
Extend the netdev_genl generic netlink family for netdev
with napi data. The napi fields exposed are:
- napi id
- queue/queue-set (both RX and TX) associated with each
   napi instance

Would you mind throwing in the IRQ vector number already?
Should be pretty easy to find the IRQ from NAPI, and it'd
make this code immediately very useful for IRQ pinning.

Sorry for the delayed response as I was on vacation.
Sure, I can add in the IRQ vector number as well in the next version of 
the series.

Additional napi fields such as PID association for napi
thread etc. can be supported in a follow-on patch set.

This series only supports 'get' ability for retrieving
napi fields (specifically, napi ids and queue[s]). The 'set'
ability for setting queue[s] associated with a napi instance
via netdev-genl will be submitted as a separate patch series.
