My current prototype implements a select action which may contain one or more buckets which in turn may contain actions. It us very much based on the select group of OpenFlow 1.4.

I will look over the proposed API more closely but nothing stands out at this time. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
