User Guidelines
An expedite queue is a strict priority queue, which is serviced until empty before
the other lower priority queues are serviced.
the weighted round robin (WRR) weight ratios are affected by the number of
expedited queues, because there are fewer queues participating in WRR. This
indicates that the corresponding weight in the wrr-queue bandwidth Interface
