1. NAME▲

mpt_register - Register protocol-specific main callback handler.

2. SYNOPSIS ▲

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

3. ARGUMENTS ▲

cbfunc
    callback function pointer

dclass
    Protocol driverAqs class (MPT_DRIVER_CLASS enum value)

func_name
    call functionAqs name

4. 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.

5. 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.
