NAME
mpt_register - Register protocol-specific main callback handler.SYNOPSIS
- u8 mpt_register(MPT_CALLBACK cbfunc, MPT_DRIVER_CLASS dclass);
ARGUMENTS
cbfunc
- callback function pointer
dclass
- Protocol driver's class (MPT_DRIVER_CLASS enum value)
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 lqnormalrq SCSI IO; one for MptScsiTaskMgmt requests; one for Scan/DV requests.
Returns u8 valued lqhandlerq 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.
