At worst, you can set up link chains that are 1 sample long (or however
long is necessary).  This is one of the possible ways that could be
implemented to handle end-of-scan events in the ni_pcimio.

On both the ni_pcimio and ni_pcidio, the DAQ-STC and MITE can cause
interrupts completely independently.
