4.2.8-ckt8 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Thadeu Lima de Souza Cascardo <cascardo@redhat.com>

commit b6ee376cb0b7fb4e7e07d6cd248bd40436fb9ba6 upstream.

When creating an ip6tnl tunnel with ip tunnel, rtnl_link_ops is not set
before ip6_tnl_create2 is called. When register_netdevice is called, there
is no linkinfo attribute in the NEWLINK message because of that.

Setting rtnl_link_ops before calling register_netdevice fixes that.

Fixes: 0b112457229d ("ip6tnl: add support of link creation via rtnl")
