QMan14 supports queuing and QoS scheduling of frames to CPUs, network interfaces and15 DPAA logic modules, maintains packet ordering within flows. Besides providing16 flow-level queuing, is also responsible for congestion management functions such17 as RED/WRED, congestion notifications and tail discards.
