  672  * A few notes about some of these functions:
  673  *
  674  * ISPCTL_FCLINK_TEST tests to make sure we have good fibre channel link.
  675  * The argument is a pointer to an integer which is the time, in microseconds,
  676  * we should wait to see whether we have good link. This test, if successful,
  677  * lets us know our connection topology and our Loop ID/AL_PA and so on.
  678  * You can't get anywhere without this.
  679  *
  680  * ISPCTL_SCAN_FABRIC queries the name server (if we're on a fabric) for
  681  * all entities using the FC Generic Services subcommand GET ALL NEXT.
  682  * For each found entity, an ISPASYNC_FABRICDEV event is generated (see
  683  * below).
  684  *
  685  * ISPCTL_SCAN_LOOP does a local loop scan. This is only done if the connection
  686  * topology is NL or FL port (private or public loop). Since the Qlogic f/w
  687  * 'automatically' manages local loop connections, this function essentially
  688  * notes the arrival, departure, and possible shuffling around of local loop
  689  * entities. Thus for each arrival and departure this generates an isp_async
  690  * event of ISPASYNC_PROMENADE (see below).
  691  *
  692  * ISPCTL_PDB_SYNC is somewhat misnamed. It actually is the final step, in
  693  * order, of ISPCTL_FCLINK_TEST, ISPCTL_SCAN_FABRIC, and ISPCTL_SCAN_LOOP.
  694  * The main purpose of ISPCTL_PDB_SYNC is to complete management of logging
  695  * and logging out of fabric devices (if one is on a fabric) and then marking
  696  * the 'loop state' as being ready to now be used for sending commands to
  697  * devices. Originally fabric name server and local loop scanning were
  698  * part of this function. It's now been separated to allow for finer control.

  725  * ISPASYNC_CHANGE_NOTIFY notifies the outer layer that a change has
  726  * occurred that invalidates the list of fabric devices known and/or
  727  * the list of known loop devices. The argument passed is a pointer
  728  * whose values are defined below  (local loop change, name server
  729  * change, other). 'Other' may simply be a LIP, or a change in
  730  * connection topology.
  731  *
  732  * ISPASYNC_FABRIC_DEV announces the next element in a list of
  733  * fabric device names we're getting out of the name server. The
  734  * argument points to a GET ALL NEXT response structure. The list
  735  * is known to terminate with an entry that refers to ourselves.
  736  * One of the main purposes of this function is to allow outer
  737  * layers, which are OS dependent, to set policy as to which fabric
  738  * devices might actually be logged into (and made visible) later
  739  * at ISPCTL_PDB_SYNC time. Since there's a finite number of fabric
  740  * devices that we can log into (256 less 3 'reserved' for F-port
  741  * topologies), and fabrics can grow up to 8 million or so entries
  742  * (24 bits of Port Address, less a wad of reserved spaces), clearly
  743  * we had better let the OS determine login policy.
  744  *
  745  * ISPASYNC_PROMENADE has an argument that is a pointer to an integer which
  746  * is an index into the portdb in the softc ('target'). Whether that entry's
  747  * valid tag is set or not says whether something has arrived or departed.
  748  * The name refers to a favorite pastime of many city dwellers- watching
  749  * people come and go, talking of Michaelangelo, and so on..
  750  *
  751  * ISPASYNC_UNHANDLED_RESPONSE gives outer layers a chance to parse a
  752  * response queue entry not otherwise handled. The outer layer should
  753  * return non-zero if it handled it. The 'arg' points to an unmassaged
  754  * response queue entry.
