-- ``Number of Queues per VF`` (default ``4``)
-
-  The number of queue per VF is determined by its host PF. If the PCI address
-  of an i40e PF is aaaa:bb.cc, the number of queues per VF can be configured
-  with EAL parameter like -w aaaa:bb.cc,queue-num-per-vf=n. The value n can be
-  1, 2, 4, 8 or 16. If no such parameter is configured, the number of queues
-  per VF is 4 by default.
