  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.
  384  *
  385  *  + There can never be two non-NIL entries which have the same dev_map_idx
  386  *    value.
