> Currently when a VF driver sends the PF a request to disable Rx queues we
> will disable them one at a time, even if the VF driver sent us a batch of
> queues to disable. This is causing issues where the Rx queue disable times
> out with LFC enabled. This can be improved by detecting when the VF is
> trying to disable all of its queues.
> 
> Also remove the variable num_qs_ena from the ice_vf structure as it was
> only used to see if there were no Rx and no Tx queues active. Instead add a
> function that checks if both the vf->rxq_ena and vf->txq_ena bitmaps are
> empty.
