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