If you're getting the drop plot, the collection is working correctly.
You'll only get delay values if the qdisc you are using reports it;
which only the codel and pie qdiscs do, unfortunately. For anything else
you'll have to infer queueing delay another way (like looking at RTT/OWD
values while running the test).

The qdisc-stats test was something I added when I initially added this
feature, and it may have bitrotted; I'll have alook. But in any case
it's not terribly useful by itself, so should probably just be removed.
