lwtunnel: per route ipv6 support for vxlan

This series enables IPv6 tunnels based on lwtunnel infrastructure. Only
vxlan is supported for now.

Tested in all combinations of IPv4 over IPv6, IPv6 over IPv4 and IPv6 over
IPv6. Applies on top of the two generic/IPv4 fixes I posted earlier today.

Jiri Benc (13):
  ip_tunnels: remove custom alignment and packing
  ip_tunnels: use u8/u16/u32
  ip_tunnels: use offsetofend
  ip_tunnels: add IPv6 addresses to ip_tunnel_key
  ip_tunnels: use tos and ttl fields also for IPv6
  route: move lwtunnel state to dst_entry
  ipv6: drop metadata dst in ip6_route_input
  ipv6: ndisc: inherit metadata dst when creating ndisc requests
  vxlan: provide access function for vxlan socket address family
  vxlan: do not shadow flags variable
  vxlan: metadata based tunneling for IPv6
  ipv6: route: extend flow representation with tunnel key
  ipv6: route: per route IP tunnel metadata via lightweight tunnel
