368 * FC Port Database entry.
369 *
370 * It has a handle that the f/w uses to address commands to a device.
371 * This handle's value may be assigned by the firmware (e.g., for local loop
372 * devices) or by the driver (e.g., for fabric devices).
373 *
374 * It has a state. If the state if VALID, that means that we've logged into
375 * the device. We also *may* have a initiator map index entry. This is a value
376 * from 0..MAX_FC_TARG that is used to index into the isp_dev_map array. If
377 * the value therein is non-zero, then that value minus one is used to index
378 * into the Port Database to find the handle for forming commands. There is
379 * back-index minus one value within to Port Database entry that tells us
380 * which entry in isp_dev_map points to us (to avoid searching).
381 *
382 * Local loop devices the firmware automatically performs PLOGI on for us
383 * (which is why that handle is imposed upon us). Fabric devices we assign
384 * a handle to and perform the PLOGI on.
385 *
386 * When a PORT DATABASE CHANGED asynchronous event occurs, we mark all VALID
387 * entries as PROBATIONAL. This allows us, if policy says to, just keep track
388 * of devices whose handles change but are otherwise the same device (and
389 * thus keep 'target' constant).
390 *
391 * In any case, we search all possible local loop handles. For each one that
392 * has a port database entity returned, we search for any PROBATIONAL entry
393 * that matches it and update as appropriate. Otherwise, as a new entry, we
394 * find room for it in the Port Database. We *try* and use the handle as the
395 * index to put it into the Database, but that's just an optimization. We mark
396 * the entry VALID and make sure that the target index is updated and correct.
397 *
398 * When we get done searching the local loop, we then search similarily for
399 * a list of devices we've gotten from the fabric name controller (if we're
400 * on a fabric). VALID marking is also done similarily.
401 *
402 * When all of this is done, we can march through the database and clean up
403 * any entry that is still PROBATIONAL (these represent devices which have
404 * departed). Then we're done and can resume normal operations.
405 *
406 * Negative invariants that we try and test for are:
407 *
408 *  + There can never be two non-NIL entries with the same { Port, Node } WWN
409 *    duples.
410 *
411 *  + There can never be two non-NIL entries with the same handle.
412 *
413 *  + There can never be two non-NIL entries which have the same dev_map_idx
414 *    value.

931 * ISPCTL_PDB_SYNC is somewhat misnamed. It actually is the final step, in

933 * The main purpose of ISPCTL_PDB_SYNC is to complete management of logging
934 * and logging out of fabric devices (if one is on a fabric) and then marking
935 * the 'loop state' as being ready to now be used for sending commands to
936 * devices. Originally fabric name server and local loop scanning were
937 * part of this function. It's now been separated to allow for finer control.
