   // In the author's experience, NDIS reports WMI data to user-space routines preceded by a 4-byte count of the number of actual data fields.
   // This is true whether a particular MOF class begins with a "count" property (as below, with Count in PassthruStatistics) or not.  Since
   // NDIS so behaves, this MOF file does in fact have each class begin with a count property so that user-space programs "know" to expect the
   // count field at the beginning of WMI data.

   // Omitting CounterType, DefaultScale and PerfDetail prevents the Count property from appearing in PerfMon (see
