Only if you enable DCB option you will get the multiple queues per VF.

Though I am not sure if understood your question, I am trying to give some comments.
Do you mean the configurable number of rx/tx queues in VF? For Niantic, hardware just supports only one queue in VF, so there is no flexibility for that. For later NICs like i40e, we will have that flexibility.
