257 * FC Port Database entry.
258 *
259 * It has a handle that the f/w uses to address commands to a device.
260 * This handle's value may be assigned by the firmware (e.g., for local loop
261 * devices) or by the driver (e.g., for fabric devices).
262 *
263 * It has a state. If the state if VALID, that means that we've logged into
264 * the device. We also *may* have a initiator map index entry. This is a value
265 * from 0..MAX_FC_TARG that is used to index into the isp_ini_map array. If
266 * the value therein is non-zero, then that value minus one is used to index
267 * into the Port Database to find the handle for forming commands. There is
268 * back-index minus one value within to Port Database entry that tells us
269 * which entry in isp_ini_map points to us (to avoid searching).
270 *
271 * Local loop devices the firmware automatically performs PLOGI on for us
272 * (which is why that handle is imposed upon us). Fabric devices we assign
273 * a handle to and perform the PLOGI on.
274 *
275 * When a PORT DATABASE CHANGED asynchronous event occurs, we mark all VALID
276 * entries as PROBATIONAL. This allows us, if policy says to, just keep track
277 * of devices whose handles change but are otherwise the same device (and
278 * thus keep 'target' constant).
279 *
280 * In any case, we search all possible local loop handles. For each one that
281 * has a port database entity returned, we search for any PROBATIONAL entry
282 * that matches it and update as appropriate. Otherwise, as a new entry, we
283 * find room for it in the Port Database. We *try* and use the handle as the
284 * index to put it into the Database, but that's just an optimization. We mark
285 * the entry VALID and make sure that the target index is updated and correct.
286 *
287 * When we get done searching the local loop, we then search similarily for
288 * a list of devices we've gotten from the fabric name controller (if we're
289 * on a fabric). VALID marking is also done similarily.
290 *
291 * When all of this is done, we can march through the database and clean up
292 * any entry that is still PROBATIONAL (these represent devices which have
293 * departed). Then we're done and can resume normal operations.
294 *
295 * Negative invariants that we try and test for are:
296 *
297 * + There can never be two non-NIL entries with the same { Port, Node } WWN
298 * duples.
299 *
300 * + There can never be two non-NIL entries with the same handle.
301 *
302 * + There can never be two non-NIL entries which have the same ini_map_idx
303 * value.
