net: ipv6: Add a flags argument to ip6tunnel_xmit(), udp_tunnel6_xmit_skb()
ip6tunnel_xmit() erases the contents of the SKB control block. In order to
be able to set particular IP6CB flags on the SKB, add a corresponding
parameter, and propagate it to udp_tunnel6_xmit_skb() as well.
In one of the following patches, VXLAN driver will use this facility to
mark packets as subject to IPv6 multicast routing.
