Implement ops needed to set MSI-X vector count on VF. sriov_get_vf_total_msix() should return total number of MSI-X that can be used by the VFs. Return the value set by devlink resources API (pf->req_msix.vf). sriov_set_msix_vec_count() will set number of MSI-X on particular VF. Disable VF register mapping, rebuild VSI with new MSI-X and queues values and enable new VF register mapping. For best performance set number of queues equal to number of MSI-X.
