From: Marek Kasiewicz <[email protected]> Allow per-queue bandwidth rate limiting to be configured without stopping the port when only a single TC node and single QoS element are involved. This enables dynamic session management where individual queue pacing rates can be changed while other queues continue transmitting.
Also fix the queue ID assignment in the bandwidth configuration to use the actual TM node ID rather than a sequential counter index, and only mark the TM hierarchy as committed when the port is stopped to permit subsequent reconfiguration.
