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.
