ipv4: Prepare rtable for IPv6 gateway
To allow the gateway to be either an IPv4 or IPv6 address, remove rt_uses_gateway from rtable and replace with rt_gw_family. If rt_gw_family is set it implies rt_uses_gateway. Rename rt_gateway to rt_gw4 to represent the IPv4 version. Signed-off-by: David Ahern <dsahern@gmail.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.
