Add a new netdev flag "rx_cpu_rmap_auto". Drivers supporting ARFS should
set the flag via netif_enable_cpu_rmap() and core will allocate and manage
the ARFS rmap. Freeing the rmap is also done by core when the netdev is
freed.

nit: rx_cpu_rmap_auto should also be added to the Kernel doc for
struct net_device.
Hi Simon,
Sure. Will also do the same for "rq_affinity_auto" in patch 3.
