[Consumption 1 DataOffset]
The number of 16-bit words into the data portion of the exchange from
which consumed data is copied. Using different offsets on different
devices allows a single exchange to be sent to a group of devices,
improving network bandwidth utilization and coordination among
devices.
To set the configuration to default, delete the file and restart the drive.
