The test sends packets and compares enqueue, transmit and Ack timestamps with expected values. It installs netem delays to increase latency between these points.
The test proves flaky in virtual environment (vng). Increase the delays to reduce variance. Scale measurement tolerance accordingly.
Time sensitive tests are difficult to calibrate. Increasing delays 10x also increases runtime 10x, for one. And it may still prove flaky at some rate.
