4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefano Brivio <sbrivio@xxxxxxxxxx>
[ Upstream commit 03080e5ec72740c1a62e6730f2a5f3f114f11b19 ]
Don't hardcode a MTU value on vti tunnel initialization,
ip_tunnel_newlink() is able to deal with this already. See also
commit ffc2b6ee4174 ("ip_gre: fix IFLA_MTU ignored on NEWLINK").
Fixes: 1181412c1a67 ("net/ipv4: VTI support new module for ip_vti.")
