248  * FC Port Database entry.
249  *
250  * It has a handle that the f/w uses to address commands to a device.
251  * This handle's value may be assigned by the firmware (e.g., for local loop
252  * devices) or by the driver (e.g., for fabric devices).
253  *
254  * It has a state. If the state if VALID, that means that we've logged into
255  * the device.
256  *
257  * Local loop devices the firmware automatically performs PLOGI on for us
258  * (which is why that handle is imposed upon us). Fabric devices we assign
259  * a handle to and perform the PLOGI on.
260  *
261  * When a PORT DATABASE CHANGED asynchronous event occurs, we mark all VALID
262  * entries as PROBATIONAL. This allows us, if policy says to, just keep track
263  * of devices whose handles change but are otherwise the same device (and
264  * thus keep 'target' constant).
265  *
266  * In any case, we search all possible local loop handles. For each one that
267  * has a port database entity returned, we search for any PROBATIONAL entry
268  * that matches it and update as appropriate. Otherwise, as a new entry, we
269  * find room for it in the Port Database. We *try* and use the handle as the
270  * index to put it into the Database, but that's just an optimization. We mark
271  * the entry VALID and make sure that the target index is updated and correct.
272  *
273  * When we get done searching the local loop, we then search similarly for
274  * a list of devices we've gotten from the fabric name controller (if we're
275  * on a fabric). VALID marking is also done similarly.
276  *
277  * When all of this is done, we can march through the database and clean up
278  * any entry that is still PROBATIONAL (these represent devices which have
279  * departed). Then we're done and can resume normal operations.
280  *
281  * Negative invariants that we try and test for are:
282  *
283  *  + There can never be two non-NIL entries with the same { Port, Node } WWN
284  *    duples.
285  *
286  *  + There can never be two non-NIL entries with the same handle.
