Public bug reported:

This rule will create flows that will direct traffic from the assigned
port based on dscp and/or 802.1p traffic into queues with configurable
bandwidth limits.

Priority queuing can be used to manage limited resources such as
bandwidth on a transmission line from a network router. In the event of
outgoing traffic queuing due to insufficient bandwidth, all other queues
can be halted to send the traffic from the highest priority queue upon
arrival. This ensures that the prioritized traffic (such as real-time
traffic, e.g. an RTP stream of a VoIP connection) is forwarded with the
least delay and the least likelihood of being rejected due to a queue
reaching its maximum capacity. All other traffic can be handled when the
highest priority queue is empty. Another approach used is to send
disproportionately more traffic from higher priority queues.
