I don't think so. test_tcp_forwarding_ip() waits for both socat processes and compares both output files before check_priority() reads the counters, so the connection is closed by then. check_dscp() reads and resets its counters the same way, and its "dscp_ingress" check also expects zero after the "dscp_none" run counted packets: check_dscp "dscp_none" "0" ... check_dscp "dscp_ingress" "$pmtu" The test passed three times out of three with the series. No change planned for this one.
