QoS Scheduling

The switch support eight CoS queues for each egress port. For each of the
eight queues, two types of scheduling can be configured: Strict Priority and
Weighted Round Robin (WRR).
Strict Priority scheduling is based on the priority of queues. Packets in a
high-priority queue are always sent first and packets in a low-priority
queue are only sent after all the high priority queues are empty.
Weighted RoundRobin (WRR) scheduling is based on the user priority
