653  *
654  * ISPCTL_FCLINK_TEST tests to make sure we have good fibre channel link.
655  * The argument is a pointer to an integer which is the time, in microseconds,
656  * we should wait to see whether we have good link. This test, if successful,
657  * lets us know our connection topology and our Loop ID/AL_PA and so on.
658  * You can't get anywhere without this.
659  *
660  * ISPCTL_SCAN_FABRIC queries the name server (if we're on a fabric) for
661  * all entities using the FC Generic Services subcommand GET ALL NEXT.
662  * For each found entity, an ISPASYNC_FABRICDEV event is generated (see
663  * below).
664  *
665  * ISPCTL_SCAN_LOOP does a local loop scan. This is only done if the connection
666  * topology is NL or FL port (private or public loop). Since the Qlogic f/w
667  * 'automatically' manages local loop connections, this function essentially
668  * notes the arrival, departure, and possible shuffling around of local loop
669  * entities. Thus for each arrival and departure this generates an isp_async
670  * event of ISPASYNC_PROMENADE (see below).
671  *
672  * ISPCTL_PDB_SYNC is somewhat misnamed. It actually is the final step, in
673  * order, of ISPCTL_FCLINK_TEST, ISPCTL_SCAN_FABRIC, and ISPCTL_SCAN_LOOP.
674  * The main purpose of ISPCTL_PDB_SYNC is to complete management of logging
675  * and logging out of fabric devices (if one is on a fabric) and then marking
676  * the 'loop state' as being ready to now be used for sending commands to
677  * devices. Originally fabric name server and local loop scanning were
678  * part of this function. It's now been separated to allow for finer control.

704  * A few notes about some of these functions:
705  *
706  * ISPASYNC_CHANGE_NOTIFY notifies the outer layer that a change has
707  * occurred that invalidates the list of fabric devices known and/or
708  * the list of known loop devices. The argument passed is a pointer
709  * whose values are defined below  (local loop change, name server
710  * change, other). 'Other' may simply be a LIP, or a change in
711  * connection topology.
712  *
713  * ISPASYNC_FABRIC_DEV announces the next element in a list of
714  * fabric device names we're getting out of the name server. The
715  * argument points to a GET ALL NEXT response structure. The list
716  * is known to terminate with an entry that refers to ourselves.
717  * One of the main purposes of this function is to allow outer
718  * layers, which are OS dependent, to set policy as to which fabric
719  * devices might actually be logged into (and made visible) later
720  * at ISPCTL_PDB_SYNC time. Since there's a finite number of fabric
721  * devices that we can log into (256 less 3 'reserved' for F-port
722  * topologies), and fabrics can grow up to 8 million or so entries
723  * (24 bits of Port Address, less a wad of reserved spaces), clearly
724  * we had better let the OS determine login policy.
725  *
726  * ISPASYNC_PROMENADE has an argument that is a pointer to an integer which
727  * is an index into the portdb in the softc ('target'). Whether that entry's
728  * valid tag is set or not says whether something has arrived or departed.
729  * The name refers to a favorite pastime of many city dwellers- watching
730  * people come and go, talking of Michaelangelo, and so on..
731  *
732  * ISPASYNC_UNHANDLED_RESPONSE gives outer layers a chance to parse a
733  * response queue entry not otherwise handled. The outer layer should
734  * return non-zero if it handled it. The 'arg' points to an unmassaged
735  * response queue entry.

856  *		HBA_BOTCH	hba botched something
857  *		HBA_CMDTIMEOUT	command timed out
858  *		HBA_SELTIMEOUT	selection timed out (also port logouts for FC)
859  *		HBA_TGTBSY	target returned a BUSY status

865  *	XS_ERR(xs)	return current error state

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