This is a situation where looking at the generated kernel datapath flows would be helpful. In your above setup, please run "ovs-dpctl dump-flows" while packets are passing through the flow, and look for datapath flows that correspond to the OpenFlow flows above. Do the datapath flows show pkt_mark (or skb_mark) being set? _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
