A single flow_cookie field in the flow_mod would not ordinarily be able to usefully serve both the purpose of matching and updating flow cookies at the same time. I think that the ability to match on flow cookies was considered more useful. The possibility of having separate flow_mod fields for matching and updating flow_cookie wasn't considered, if I recall correctly. _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
