Add a test case to validate the interaction between TBF and SKBPRIO queueing disciplines, specifically targeting queue length accounting corner cases. This test complements the fix for the queue length accounting issue in the SKBPRIO qdisc. This is still best-effort, as timing and manipulating enqueue and dequeue from user-space is very hard.
