Summary

The main purpose of this test is to verify that we can use ALTQ on top
of if_vlan, but while we're here we also exercise the CBQ code. There's
already a basis test for HFSC, so it makes sense to test another
algorithm while we test if_vlan.

How do you ensure, that the packets send before are still not delivered, so the queue is empty now? Looks like an scheduling dependency race condition.

How about:

  • prefill the queue (like now)
  • the secondary ping tries to send multiple packets within a short interval
  • check, if all packets of the secondary ping are received back

Make the test slightly more robust by sending 5 packets, all of which we expect
to get dropped and allowing one to make it through.
