643  * A few notes about some of these functions:
644  *
645  * ISPCTL_FCLINK_TEST tests to make sure we have good fibre channel link.
646  * The argument is a pointer to an integer which is the time, in microseconds,
647  * we should wait to see whether we have good link. This test, if successful,
648  * lets us know our connection topology and our Loop ID/AL_PA and so on.
649  * You can't get anywhere without this.
650  *
651  * ISPCTL_SCAN_FABRIC queries the name server (if we're on a fabric) for
652  * all entities using the FC Generic Services subcommand GET ALL NEXT.
653  * For each found entity, an ISPASYNC_FABRICDEV event is generated (see
654  * below).
655  *
656  * ISPCTL_SCAN_LOOP does a local loop scan. This is only done if the connection
657  * topology is NL or FL port (private or public loop). Since the Qlogic f/w
658  * 'automatically' manages local loop connections, this function essentially
659  * notes the arrival, departure, and possible shuffling around of local loop
660  * entities. Thus for each arrival and departure this generates an isp_async
661  * event of ISPASYNC_PROMENADE (see below).
662  *
663  * ISPCTL_PDB_SYNC is somewhat misnamed. It actually is the final step, in
664  * order, of ISPCTL_FCLINK_TEST, ISPCTL_SCAN_FABRIC, and ISPCTL_SCAN_LOOP.
665  * The main purpose of ISPCTL_PDB_SYNC is to complete management of logging
666  * and logging out of fabric devices (if one is on a fabric) and then marking
667  * the 'loop state' as being ready to now be used for sending commands to
668  * devices. Originally fabric name server and local loop scanning were
669  * part of this function. It's now been separated to allow for finer control.

694  * A few notes about some of these functions:
695  *
696  * ISPASYNC_CHANGE_NOTIFY notifies the outer layer that a change has
697  * occurred that invalidates the list of fabric devices known and/or
698  * the list of known loop devices. The argument passed is a pointer
699  * whose values are defined below  (local loop change, name server
700  * change, other). 'Other' may simply be a LIP, or a change in
701  * connection topology.
702  *
703  * ISPASYNC_FABRIC_DEV announces the next element in a list of
704  * fabric device names we're getting out of the name server. The
705  * argument points to a GET ALL NEXT response structure. The list
706  * is known to terminate with an entry that refers to ourselves.
707  * One of the main purposes of this function is to allow outer
708  * layers, which are OS dependent, to set policy as to which fabric
709  * devices might actually be logged into (and made visible) later
710  * at ISPCTL_PDB_SYNC time. Since there's a finite number of fabric
711  * devices that we can log into (256 less 3 'reserved' for F-port
712  * topologies), and fabrics can grow up to 8 million or so entries
713  * (24 bits of Port Address, less a wad of reserved spaces), clearly
714  * we had better let the OS determine login policy.
715  *
716  * ISPASYNC_PROMENADE has an argument that is a pointer to an integer which
717  * is an index into the portdb in the softc ('target'). Whether that entry's
718  * valid tag is set or not says whether something has arrived or departed.
719  * The name refers to a favorite pastime of many city dwellers- watching
720  * people come and go, talking of Michaelangelo, and so on..
721  *
722  * ISPASYNC_UNHANDLED_RESPONSE gives outer layers a chance to parse a
723  * response queue entry not otherwise handled. The outer layer should
724  * return non-zero if it handled it. The 'arg' points to an unmassaged
725  * response queue entry.

849  *		HBA_NOERROR	command has no erros
850  *		HBA_BOTCH	hba botched something
851  *		HBA_CMDTIMEOUT	command timed out
852  *		HBA_SELTIMEOUT	selection timed out (also port logouts for FC)
853  *		HBA_TGTBSY	target returned a BUSY status
854  *		HBA_BUSRESET	bus reset destroyed command
855  *		HBA_ABORTED	command was aborted (by request)
856  *		HBA_DATAOVR	a data overrun was detected
857  *		HBA_ARQFAIL	Automatic Request Sense failed

859  *	XS_ERR(xs)	return current error state
860  *	XS_NOERR(xs)	there is no error currently set

863  *	XS_SAVE_SENSE(xs, sp)		save sense data
864  *

867  *

869  *	DEFAULT_IID(struct ispsoftc *)		Default SCSI initiator ID
870  *	DEFAULT_LOOPID(struct ispsoftc *)	Default FC Loop ID
871  *	DEFAULT_NODEWWN(struct ispsoftc *)	Default Node WWN
872  *	DEFAULT_PORTWWN(struct ispsoftc *)	Default Port WWN
873  *	DEFAULT_FRAMESIZE(struct ispsoftc *)	Default Frame Size
874  *	DEFAULT_EXEC_THROTTLE(struct ispsoftc *) Default Execution Throttle
875  *		These establish reasonable defaults for each platform.
876  * 		These must be available independent of card NVRAM and are
877  *		to be used should NVRAM not be readable.
878  *
879  *	ISP_NODEWWN(struct ispsoftc *)	FC Node WWN to use
880  *	ISP_PORTWWN(struct ispsoftc *)	FC Port WWN to use
881  *
882  *		These are to be used after NVRAM is read. The tags
883  *		in fcparam.isp_{node,port}wwn reflect the values
884  *		read from NVRAM (possibly corrected for card botches).
885  *		Each platform can take that information and override
886  *		it or ignore and return the Node and Port WWNs to be
887  * 		used when sending the Qlogic f/w the Initialization Control
888  *		Block.
