850 * Performa a port login/logout
763 *
851 *
764 * ISPCTL_FCLINK_TEST tests to make sure we have good fibre channel link.
765 * The argument is a pointer to an integer which is the time, in microseconds,
766 * we should wait to see whether we have good link. This test, if successful,
767 * lets us know our connection topology and our Loop ID/AL_PA and so on.
768 * You can't get anywhere without this.
769 *
770 * ISPCTL_SCAN_FABRIC queries the name server (if we're on a fabric) for
771 * all entities using the FC Generic Services subcommand GET ALL NEXT.
772 * For each found entity, an ISPASYNC_FABRICDEV event is generated (see
773 * below).
774 *
775 * ISPCTL_SCAN_LOOP does a local loop scan. This is only done if the connection
776 * topology is NL or FL port (private or public loop). Since the Qlogic f/w
777 * 'automatically' manages local loop connections, this function essentially
778 * notes the arrival, departure, and possible shuffling around of local loop
779 * entities. Thus for each arrival and departure this generates an isp_async

785 * and logging out of fabric devices (if one is on a fabric) and then marking
786 * the 'loop state' as being ready to now be used for sending commands to

815 * A few notes about some of these functions:
816 *
817 * ISPASYNC_CHANGE_NOTIFY notifies the outer layer that a change has
818 * occurred that invalidates the list of fabric devices known and/or
819 * the list of known loop devices. The argument passed is a pointer
820 * whose values are defined below (local loop change, name server
821 * change, other). 'Other' may simply be a LIP, or a change in
822 * connection topology.
823 *
824 * ISPASYNC_FABRIC_DEV announces the next element in a list of
825 * fabric device names we're getting out of the name server. The
826 * argument points to a GET ALL NEXT response structure. The list
827 * is known to terminate with an entry that refers to ourselves.
828 * One of the main purposes of this function is to allow outer
829 * layers, which are OS dependent, to set policy as to which fabric
830 * devices might actually be logged into (and made visible) later
831 * at ISPCTL_PDB_SYNC time. Since there's a finite number of fabric
832 * devices that we can log into (256 less 3 'reserved' for F-port
833 * topologies), and fabrics can grow up to 8 million or so entries
834 * (24 bits of Port Address, less a wad of reserved spaces), clearly
835 * we had better let the OS determine login policy.
836 *
837 * ISPASYNC_PROMENADE has an argument that is a pointer to an integer which
838 * is an index into the portdb in the softc ('target'). Whether that entry's
839 * valid tag is set or not says whether something has arrived or departed.
840 * The name refers to a favorite pastime of many city dwellers- watching
841 * people come and go, talking of Michaelangelo, and so on..
842 *
843 * ISPASYNC_UNHANDLED_RESPONSE gives outer layers a chance to parse a
844 * response queue entry not otherwise handled. The outer layer should
845 * return non-zero if it handled it. The 'arg' points to an unmassaged
846 * response queue entry.
