23 This routine is called by a protocol-specific driver (SCSI host, LAN,
24 SCSI target) to register its reply callback routine. Each
25 protocol-specific driver must do this before it will be able to use any
26 IOC resources, such as obtaining request frames.
27
29 The SCSI protocol driver currently calls this routine thrice in order
30 to register separate callbacks; one for “normal” SCSI IO; one for
31 MptScsiTaskMgmt requests; one for Scan/DV requests.
32
33 Returns u8 valued “handle” in the range (and S.O.D. order)
34 {N,...,7,6,5,...,1} if successful. A return value of
35 MPT_MAX_PROTOCOL_DRIVERS (including zero!) should be considered an
36 error by the caller.
