The queuing policy for each port is by default priority queuing.
In priority queuing, each flow is assigned a priority. The higher
priority flows go first. Within the priority queue, the flows
are serviced in a first in first out order. If the higher priority
queue is never empty, the other queues would starve. In fair
queuing, each priority queue is serviced in a round-robin fashion.
Weighted fair queuing is fair queing for which each queue is
weighted. On the RS platform, priorityQueuing is known as
strict priority (SP).
