idata (instance data)
The term idata has two distinct meanings
for SVR5 drivers:
Beginning with DDI version 8,
specific devices are identified by
the idata and channel rather than by
device number as in earlier releases.
idata is returned by the CFG_ADD subfunction
entry point routine. See
SDI HBA drivers use idata as shorthand
to refer to the
structure and it's similarly named predecessors.
This structure contains information
that is specific to a given instance of
a target (peripheral) device that is supported
by the HBA driver.
