Yes, of course. The problem is that when IPv4 is not explicitly defined using GROUP/LOCAL attributes, there are a lot of places that take IPv6 path. So, what I'm proposing is to explicitly set default_dst family to AF_INET and override it with AF_INET6 only when IPv6 is explicitly requested. -- Sincerely yours, Mike. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
