====================
tun: add the RFS support

Since Tom Herbert's hash related patchset was modified and got merged,
his pachset about adding support for RFS on tun flows also need to get
adjusted accordingly. I tried to update them, and before i will start
to do some perf tests, i hope to get one correct code base, so it's time
to post them out now. Any constructive comments are welcome, thanks.

      tun: Add support for RFS on tun flows · 9bc88939
      由 Tom Herbert 提交于 
      This patch adds support so that the rps_flow_tables (RFS) can be
programmed using the tun flows which are already set up to track flows
for the purposes of queue selection.

On the receive path (corresponding to select_queue and tun_net_xmit) the
rxhash is saved in the flow_entry.  The original code only does flow
lookup in select_queue, so this patch adds a flow lookup in tun_net_xmit
if num_queues == 1 (select_queue is not called from
dev_queue_xmit->netdev_pick_tx in that case).

The flow is recorded (processing CPU) in tun_flow_update (TX path), and
reset when flow is deleted.

      net: Allow setting sock flow hash without a sock · fe477558
      由 Tom Herbert 提交于 
      This patch adds sock_rps_record_flow_hash and sock_rps_reset_flow_hash
which take a hash value as an argument and sets the sock_flow_table
accordingly.  This allows the table to be populated in cases where flow
is being tracked outside of a sock structure.

sock_rps_record_flow and sock_rps_reset_flow call this function
where the hash is taken from sk_rxhash.
