net: Changes to ip_tunnel to support foo-over-udp encapsulation
This patch changes IP tunnel to support (secondary) encapsulation,
Foo-over-UDP. Changes include:
1) Adding tun_hlen as the tunnel header length, encap_hlen as the
encapsulation header length, and hlen becomes the grand total
of these.
2) Added common netlink define to support FOU encapsulation.
3) Routines to perform FOU encapsulation.
