Recently added ERSAPN feature introduced changes in ip6_gre, ip6_tunnel,
and ip_gre which will break build on RHEL 7.5 kernel because of
ndo_change_mtu(). This patch fixes the issue in RHEL 7.5 kernel.
Fixes: 8e53509c ("gre: introduce native tunnel support for ERSPAN")
Fixes: c387d817 ("compat: Add ipv6 GRE and IPV6 Tunneling")
