I think what you are most likely seeing is a difference between flow translation and flow execution. The "metadata" field (and other metadata fields like reg0...reg15) are only significant during the flow translation step. They do not generally matter for execution, so they get discarded. Your new feature is introducing a need for the field in question at execution time. The way to deal with that is probably to save the metadata field at translation time and pass it to the userspace ipfix action. You could put it in, for example, the ipfix member of struct user_action_cookie. _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
