These captures don't line up - there are no SYN packets at the beginning of the second log and they are also 20ms apart - so you can't really draw a conclusion from it. You're going to need to do any further debugging on this yourself as it seems TSO packets do indeed get through the entire system. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
