Add the ixgbe driver code implementing ndo_ll_poll.
It should be easy for other drivers to do something similar
in order to enable support for CONFIG_INET_LL_RX_POLL

Yes... in fact I wonder whether the lock and state couldn't be added to
napi_struct instead of being driver-specific.

That would potentially allow GRO to detect that it's being called in
low-latency context...

Not sure we have to add another test in fast path.

Users wanting polling support should disable GRO (ethtool -K eth0 gro
off)

Doing this dynamically would be nice of course.
