<p>Get device statistics, scoped to a device or a queue.
These statistics extend (and partially duplicate) statistics available

Value of the <cite>scope</cite> attribute determines how statistics are
aggregated. When aggregated for the entire device the statistics
represent the total number of events since last explicit reset of
the device (i.e. not a reconfiguration like changing queue count).
When reported per-queue, however, the statistics may not add
up to the total number of events, will only be reported for currently
active objects, and will likely report the number of events since last
reconfiguration.</p>
