udp_tunnel: Pass UDP socket down through udp_tunnel{, 6}_xmit_skb().
That was we can make sure the output path of ipv4/ipv6 operate on the UDP socket rather than whatever random thing happens to be in skb->sk. Based upon a patch by Jiri Pirko. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Hannes Frederic Sowa <hannes@stressinduktion.org>
