Merge branch 'tunnels'
Nicolas Dichtel says: ==================== tunnels: don't allow to add the same tunnel twice This series fixes the check of an existing tunnel with the same parameters when a new tunnel is added. I've checked all users of ip_tunnel_newlink(): gre, gretap, ipip and vti. The bug exists only for gre and vti. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
