ipv4: Add support to fib_config for IPv6 gateway
Add support for an IPv6 gateway to fib_config. Since a gateway is either IPv4 or IPv6, make it a union with fc_gw4 where fc_gw_family decides which address is in use. Update current checks on family and gw4 to handle ipv6 as well. Signed-off-by: David Ahern <dsahern@gmail.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.
