queue-num-per-vf is the reserved queue number by PF for VF, it fit the situation when fixed queue number is required, so I think we still can keep it.
but I think the document could be modified properly , since queue-num-per-vf is never be the upper boundary of the queue number per vf,
pf still can allocate max to 16 queues to exceed, we can add this explanation.
