vDPA: check VIRTIO_NET_F_RSS for max_virtqueue_paris's presence
virtio 1.2 spec says: max_virtqueue_pairs only exists if VIRTIO_NET_F_MQ or VIRTIO_NET_F_RSS is set. So when reporint MQ to userspace, it should check both VIRTIO_NET_F_MQ and VIRTIO_NET_F_RSS. unused parameter struct vdpa_device *vdev is removed Signed-off-by: Zhu Lingshan <lingshan.zhu@intel.com> Acked-by: Jason Wang <jasowang@redhat.com> Message-Id: <20220929014555.112323-4-lingshan.zhu@intel.com> Signed-off-by: Michael S.
