ipv4: Add support to rtable for ipv6 gateway
Add support for an IPv6 gateway to rtable. Since a gateway is either IPv4 or IPv6, make it a union with rt_gw4 where rt_gw_family decides which address is in use. When dumping the route data, encode an ipv6 nexthop using RTA_VIA. Signed-off-by: David Ahern <dsahern@gmail.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.
