An operations index (ops_idx) is a non-zero integer,
assigned by the driver to uniquely identify a set of
entry-point related properties defined in a udi_ops_init_t structure.
An array of these structures is used to define all the channel
operations for a source module, and the ops_idx) member of
each is used as a unique identifier.

These indexes are used in the ``Channel operations initialization'' section.
