Most packets don't ever go to userspace so you'll have to instrument the kernel module, probably the ovs_dp_process_packet() function in datapath/datapath.h. I don't know the best way to do this. You might be able to approximate this with the Linux "perf" tool. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
