Solaris DDI specific (Solaris DDI).
.SH DESCRIPTION
.sp
.LP
The \fBnet_instance_t\fR data structure defines a collection of instances to be
called when relevant events happen within \fBIP\fR. The value returned by the
\fBnin_create()\fR function is stored internally and passed back to both the
\fBnin_destroy()\fR and \fBnin_shutdown()\fR functions as the second argument.
The \fBnetid_t\fR passed through to each function can be used to uniquely
identify each instance of \fBIP\fR.
