NAME
       mpt_register - Register protocol-specific main callback handler.

SYNOPSIS
       u8 mpt_register(MPT_CALLBACK cbfunc, MPT_DRIVER_CLASS dclass, char * func_name);

ARGUMENTS
       cbfunc
           callback function pointer

       dclass
           Protocol driver's class (MPT_DRIVER_CLASS enum value)

       func_name
           call function's name

DESCRIPTION
       This routine is called by a protocol-specific driver (SCSI host, LAN, SCSI target) to
       register its 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.

NOTES
       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.

       Returns u8 valued “handle” in the range (and S.O.D. order) {N,...,7,6,5,...,1} if
       successful. A return value of MPT_MAX_PROTOCOL_DRIVERS (including zero!) should be
       considered an error by the caller.
