Thanks! How did you know that my preferred method of reading
hierarchies is looking at a linear output!? 😕
Anyway. My gut feeling is that this is cutting a corner. Seems
most natural for the VF/PF level to be controlled by the admin
and the queue level by whoever owns the queue. The hypervisor
driver/FW should reconcile the two and compile the full hierarchy.
