Yes, this is unfortunate. I think the first option is the best, since this is the new OpenFlow standard way of calling that port, so it's likely to only lead to more confusion going forward. I sort of doubt that that many people use the "ANY" syntax, since fields are implicitly wildcarded if not specified. If we go this route, we should drop support for wildcarding with "ANY" on fields, since that will be *really* confusing. I think it still makes sense to support "*", though, so users can still explicitly wildcard a field if they want. --Justin _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
