458 * If you set ISP_ROLE_NONE, the cards will be reset, new firmware loaded,
459 * NVRAM read, and defaults set, but any further initialization (e.g.
460 * INITIALIZE CONTROL BLOCK commands for 2X00 cards) won't be done.
461 *
462 * If INITIATOR MODE isn't set, attempts to run commands will be stopped
463 * at isp_start and completed with the moral equivalent of SELECTION TIMEOUT.
464 *
465 * If TARGET MODE is set, it doesn't mean that the rest of target mode support
466 * needs to be enabled, or will even work. What happens with the 2X00 cards
467 * here is that if you have enabled it with TARGET MODE as part of the ICB
468 * options, but you haven't given the f/w any ram resources for ATIOs or
469 * Immediate Notifies, the f/w just handles what it can and you never see
470 * anything. Basically, it sends a single byte of data (the first byte,
471 * which you can set as part of the INITIALIZE CONTROL BLOCK command) for
472 * INQUIRY, and sends back QUEUE FULL status for any other command.

631 *
632 * A few notes about some of these functions:
633 *
634 * ISPCTL_FCLINK_TEST tests to make sure we have good fibre channel link.
635 * The argument is a pointer to an integer which is the time, in microseconds,
636 * we should wait to see whether we have good link. This test, if successful,
637 * lets us know our connection topology and our Loop ID/AL_PA and so on.
638 * You can't get anywhere without this.
639 *
640 * ISPCTL_SCAN_FABRIC queries the name server (if we're on a fabric) for
641 * all entities using the FC Generic Services subcommand GET ALL NEXT.
642 * For each found entity, an ISPASYNC_FABRICDEV event is generated (see
643 * below).
644 *
645 * ISPCTL_SCAN_LOOP does a local loop scan. This is only done if the connection
646 * topology is NL or FL port (private or public loop). Since the Qlogic f/w
647 * 'automatically' manages local loop connections, this function essentially
648 * notes the arrival, departure, and possible shuffling around of local loop
649 * entities. Thus for each arrival and departure this generates an isp_async
650 * event of ISPASYNC_PROMENADE (see below).
651 *
652 * ISPCTL_PDB_SYNC is somewhat misnamed. It actually is the final step, in
653 * order, of ISPCTL_FCLINK_TEST, ISPCTL_SCAN_FABRIC, and ISPCTL_SCAN_LOOP.
654 * The main purpose of ISPCTL_PDB_SYNC is to complete management of logging
655 * and logging out of fabric devices (if one is on a fabric) and then marking
656 * the 'loop state' as being ready to now be used for sending commands to
657 * devices. Originally fabric name server and local loop scanning were
658 * part of this function. It's now been separated to allow for finer control.

684 * A few notes about some of these functions:
685 *
686 * ISPASYNC_CHANGE_NOTIFY notifies the outer layer that a change has
687 * occurred that invalidates the list of fabric devices known and/or
688 * the list of known loop devices. The argument passed is a pointer
689 * whose values are defined below  (local loop change, name server
690 * change, other). 'Other' may simply be a LIP, or a change in
691 * connection topology.
692 *
693 * ISPASYNC_FABRIC_DEV announces the next element in a list of
694 * fabric device names we're getting out of the name server. The
695 * argument points to a GET ALL NEXT response structure. The list
696 * is known to terminate with an entry that refers to ourselves.
697 * One of the main purposes of this function is to allow outer
698 * layers, which are OS dependent, to set policy as to which fabric
699 * devices might actually be logged into (and made visible) later
700 * at ISPCTL_PDB_SYNC time. Since there's a finite number of fabric
701 * devices that we can log into (256 less 3 'reserved' for F-port
702 * topologies), and fabrics can grow up to 8 million or so entries
703 * (24 bits of Port Address, less a wad of reserved spaces), clearly
704 * we had better let the OS determine login policy.
705 *
706 * ISPASYNC_PROMENADE has an argument that is a pointer to an integer which
707 * is an index into the portdb in the softc ('target'). Whether that entry's
708 * valid tag is set or not says whether something has arrived or departed.
709 * The name refers to a favorite pastime of many city dwellers- watching
710 * people come and go, talking of Michaelangelo, and so on..
711 *
712 * ISPASYNC_UNHANDLED_RESPONSE gives outer layers a chance to parse a
713 * response queue entry not otherwise handled. The outer layer should
714 * return non-zero if it handled it. The 'arg' points to an unmassaged
715 * response queue entry.
