The busy polling socket option adds support for sockets to busy wait on data
arriving on the napi queue from which they have most recently received a frame.
Currently only tcp and udp support this feature, but theres no reason sctp can't
do so as well. Add it in so appliations can take advantage of it

Hi Neil
Do we gain anything by polling?
This is probably more appropriate for net-next...

Yes, for high througput applications, we save the latency introduced by
processing the interrupt and waiting for the scheduled napi poll to run. See
the initial busy poll patch series for intel performance numbers.
