This doesn't seem to have anything to do with OVS. I believe that when TC drops a packet, the drops will be accounted by the packet scheduler rather than by the interface, so you should be able to use some "tc -s" command to view drops. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
