This is only done if the connection * topology is NL or FL port (private or public loop). Since the Qlogic f/w * 'automatically' manages local loop connections, this function essentially * notes the arrival, departure, and possible shuffling around of local loop * entities. Thus for each arrival and departure this generates an isp_async * event of ISPASYNC_PROMENADE (see below). * * ISPCTL_PDB_SYNC is somewhat misnamed. It actually is the final step, in * order, of ISPCTL_FCLINK_TEST, ISPCTL_SCAN_FABRIC, and ISPCTL_SCAN_LOOP. * The main purpose of ISPCTL_PDB_SYNC is to complete management of logging * and logging out of fabric devices (if one is on a fabric) and then marking * the 'loop state' as being ready to now be used for sending commands to * devices. Originally fabric name server and local loop scanning were * part of this function.

The argument passed is a pointer * whose values are defined below (local loop change, name server * change, other). 'Other' may simply be a LIP, or a change in * connection topology. * * ISPASYNC_FABRIC_DEV announces the next element in a list of * fabric device names we're getting out of the name server.

Since there's a finite number of fabric * devices that we can log into (256 less 3 'reserved' for F-port * topologies), and fabrics can grow up to 8 million or so entries * (24 bits of Port Address, less a wad of reserved spaces), clearly * we had better let the OS determine login policy. * * ISPASYNC_PROMENADE has an argument that is a pointer to an integer which * is an index into the portdb in the softc ('target'). Whether that entrie's * valid tag is set or not says whether something has arrived or departed. * The name refers to a favorite pastime of many city dwellers- watching * people come and go, talking of Michaelangelo, and so on.. * * ISPASYNC_UNHANDLED_RESPONSE gives outer layers a chance to parse a * response queue entry not otherwise handled.
