Why (nb_ethdev * nb_stages) number of Queues?
I had expected if the test is for eventdev with Q queues, P ports, that that Q number of stages is all that is required, (possibly with +1 for TX queue, iirc some HW doesn't require the TX Queue).
Am I missing something here? I've left the code snippet I don't understand below.

Mandatory arguments seem pointless to me, unless there are other valid options to choose from.

As per comment above, this is what I don't understand? Why more queues than stages?
