Merge branch 'so_incoming_cpu'
Eric Dumazet says:
====================
net: SO_INCOMING_CPU support
SO_INCOMING_CPU socket option (read by getsockopt()) provides
an alternative to RPS/RFS for high performance servers using
multi queues NIC.
TCP should use sk_mark_napi_id() for established sockets only.
