> Currently the VF gets a default number of allocated queues from HW on init
> and it could choose to enable or disable those allocated queues.
> This makes it such that the VF can request more or less underlying allocated
> queues from the PF.
> 
> First the VF negotiates the number of queues it wants that can be supported
> by the PF and if successful asks for a reset.  During reset the PF will reallocate
> the HW queues for the VF and will then remap the new queues.
