         The driver uses this to selectively prevent the device from executing requests from this virtqueue.
+        If the driver negotiates VIRTIO_F_RING_ENABLE_ANYTIME or
+        VIRTIO_F_RING_RESET, the driver writes 1 to this field to enable a
+        virtqueue.  See \ref{sec:Basic Facilities of a Virtio Device / Virtqueues / Selective Virtqueue Enable}
+        and \ref{sec:Basic Facilities of a Virtio Device / Virtqueues / Virtqueue Reset}.
         1 - enabled; 0 - disabled.
