ip6_tunnel: add optional fwmark inherit
Add IP6_TNL_F_USE_ORIG_FWMARK to ip6_tunnel, so that ip6_tnl_xmit2()
makes a route lookup taking into account skb->fwmark and doesnt cache
lookup result.
This permits more flexibility in policies and firewall setups.
To setup such a tunnel, "fwmark inherit" option should be added to "ip
-f inet6 tunnel" command.
