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

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
1.59 mjacob 746: * is an index into the portdb in the softc ('target'). Whether that entry's
1.41 mjacob 747: * valid tag is set or not says whether something has arrived or departed.
