> 
> This is a pipeline queue test case that aims at testing the following:
> 1. Measure the end-to-end performance of an event dev with a ethernet dev.
> 2. Maintain packet ordering from Rx to Tx.
> 
> The pipeline queue test configures the eventdev with Q queues and P ports,
> where Q is (nb_ethdev * nb_stages) + nb_ethdev and P is nb_workers.
> 
> The user can choose the number of workers and number of stages through the
> --wlcores and the --stlist application command line arguments respectively.
> The probed ethernet devices act as producer(s) for this application.
> 
> The ethdevs are configured as event Rx adapters that enables them to
> injects events to eventdev based the first stage schedule type list
> requested by the user through --stlist the command line argument.
> 
> Based on the number of stages to process(selected through --stlist),
> the application forwards the event to next upstream queue and when it
> reaches last stage in the pipeline if the event type is ATOMIC it is
> enqueued onto ethdev Tx queue else to maintain ordering the event type is
> set to ATOMIC and enqueued onto the last stage queue.
> On packet Tx, application increments the number events processed and print
> periodically in one second to get the number of events processed in one
> second.
> 
> Note: The --prod_type_ethdev is mandatory for running the application.
> 
> Example command to run pipeline queue test:
> sudo build/app/dpdk-test-eventdev -c 0xf -s 0x8 --vdev=event_sw0 -- \
> --test=pipeline_queue --wlcore=1 --prod_type_ethdev --stlist=ao
