The main goal of translation is to come up with a set of datapath actions that can implement the OpenFlow actions. The packet is supplied in case it contains needed information not in the flow, but it's not the focus of translation. Thus, the usual way to modify a packet would be to implement a new datapath action and then add that action to the set of datapath actions at translation time. The translations of flows without packets that you're seeing are part of "revalidation", which is used to check that the cache is still accurate. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
