/*
* 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.
*
* 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 similarly for
* a list of devices we've gotten from the fabric name controller (if we're
* on a fabric). VALID marking is also done similarly.
*
* 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.

* Immediate Notifies, the f/w just handles what it can and you never see
* anything. Basically, it sends a single byte of data (the first byte,
* which you can set as part of the INITIALIZE CONTROL BLOCK command) for
* INQUIRY, and sends back QUEUE FULL status for any other command.
