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

Hi Pawel
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.

Helin
