> Unlike the XL710 series, 800-series hardware can allocate more than 4 MSI-X
> vectors per VF. This patch enables that functionality. We dynamically allocate
> vectors and queues depending on how many VFs are enabled. Allocating the
> maximum number of VFs replicates XL710 behavior with 4 queues and 4
> vectors. But allocating a smaller number of VFs will give you 16 queues and 16
> vectors.
