Protocol driver's class (MPT_DRIVER_CLASS enum value)
.SH "DESCRIPTION"
.PP
This routine is called by a protocol-specific driver (SCSI host,
LAN, SCSI target) to register it's reply callback routine.  Each
protocol-specific driver must do this before it will be able to
use any IOC resources, such as obtaining request frames.
.SH "NOTES"
.PP
The SCSI protocol driver currently calls this routine thrice
in order to register separate callbacks; one for ``normal'' SCSI IO;
one for MptScsiTaskMgmt requests; one for Scan/DV requests.
.PP
Returns a positive integer valued ``handle'' in the
range (and S.O.D. order) {N,...,7,6,5,...,1} if successful.
Any non-positive return value (including zero!) should be considered
an error by the caller.
