Subject: [PATCH net 0/3] net: fix IFLA_MTU ignored on NEWLINK for some ip and ipv6 tunnels

The fix for ip_gre follows the way other ip tunnels do: not to
set mtu in ndo_init, as ip_tunnel_newlink will take care of it
properly.

The fix for ip6_tunnel and sit follows the way ipv6 tunenls do:
to set mtu again according to IFLA_MTU after, as all bind_dev
are called in ndo_init where it can't get the tb[IFLA_MTU].

Xin Long (3):
  ip_gre: fix IFLA_MTU ignored on NEWLINK
  ip6_tunnel: fix IFLA_MTU ignored on NEWLINK
  sit: fix IFLA_MTU ignored on NEWLINK
