Before I can suggest any code patches, additional experiment is needed to
confirm or reject the hypothesis in
If you want to measure RTT changes due to route changes, one possible way
is to increase the link delay.
When the link delay is 10ms, a 10ms RTT change is 50% and appears
When the link delay is 500ms, a 10ms RTT change is 1% and appears
