For me kernel warning sounds like a reasonable approach. I will change the patch to not drop the request with error, but to issue a warning instead. I'll also try using better email client next time. Furthermore I believe that most tools used for both IPv4 and IPv6 routing (like iproute) do add the CREATE flag because IPv4 route creation does require it. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
