Tom Herbert 4565e9919c gre: Setup and TX path for gre/UDP foo-over-udp encapsulation
Added netlink attrs to configure FOU encapsulation for GRE, netlink
handling of these flags, and properly adjust MTU for encapsulation.
ip_tunnel_encap is called from ip_tunnel_xmit to actually perform FOU
encapsulation.
