[dpdk-dev] DPDK Enqueue Pipeline

Hi all,
The DPDK QoS scheduler has a 4-stage pipeline for enqueuing the packets.
This is used for hiding the latency of prefetching the data structures.
Why is there no pipeline for dequeuing the packets?
How does the dequeue function maintain the state of a packet? In other
words, if I want to backtrace the packet that is dequeued to get the info
of what was the traffic class and from which queue the packet was dequeued.
Is there any way to get this.

Regards
