340  * FC Port Database entry.
341  *
342  * It has a handle that the f/w uses to address commands to a device.
343  * This handle's value may be assigned by the firmware (e.g., for local loop
344  * devices) or by the driver (e.g., for fabric devices).
345  *
346  * It has a state. If the state if VALID, that means that we've logged into
347  * the device. We also *may* have a initiator map index entry. This is a value
348  * from 0..MAX_FC_TARG that is used to index into the isp_dev_map array. If
349  * the value therein is non-zero, then that value minus one is used to index
350  * into the Port Database to find the handle for forming commands. There is
351  * back-index minus one value within to Port Database entry that tells us
352  * which entry in isp_dev_map points to us (to avoid searching).
353  *
354  * Local loop devices the firmware automatically performs PLOGI on for us
355  * (which is why that handle is imposed upon us). Fabric devices we assign
356  * a handle to and perform the PLOGI on.
357  *
358  * When a PORT DATABASE CHANGED asynchronous event occurs, we mark all VALID
359  * entries as PROBATIONAL. This allows us, if policy says to, just keep track
360  * of devices whose handles change but are otherwise the same device (and
361  * thus keep 'target' constant).
362  *
363  * In any case, we search all possible local loop handles. For each one that
364  * has a port database entity returned, we search for any PROBATIONAL entry
365  * that matches it and update as appropriate. Otherwise, as a new entry, we
366  * find room for it in the Port Database. We *try* and use the handle as the
367  * index to put it into the Database, but that's just an optimization. We mark
368  * the entry VALID and make sure that the target index is updated and correct.
369  *
370  * When we get done searching the local loop, we then search similarily for
371  * a list of devices we've gotten from the fabric name controller (if we're
372  * on a fabric). VALID marking is also done similarily.
373  *
374  * When all of this is done, we can march through the database and clean up
375  * any entry that is still PROBATIONAL (these represent devices which have
376  * departed). Then we're done and can resume normal operations.
377  *
378  * Negative invariants that we try and test for are:
379  *
380  *  + There can never be two non-NIL entries with the same { Port, Node } WWN
381  *    duples.
382  *
383  *  + There can never be two non-NIL entries with the same handle.

386  *    value.
