Appendix B.1. Driver Stats
The statistics recorded by the
Fragment Ack/nack messages are NOT counted as messages but the bytes sent/rcvd are counted.
Connection messages are counted as messages and the bytes sent/rcvd are counted.
This driver can expose these and additional statistics by writing data to a Data Array.
A special Map Descriptor is required. The driver recognizes the Map Descriptor by its name which must be

When the driver sees this Map Descriptor it uses the Data Array SNP_STATS (in this example) to store driver specific statistics. Only one of these Map Descriptors may be specified (per tier) per FieldServer.
The driver stores the following stats for each port.. The offset into the Data Array can be found by multiplying the port number by 60
