248 * FC Port Database entry.
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).
254 * It has a state. If the state if VALID, that means that we've logged into
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.
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).
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.
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.
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.
281 * Negative invariants that we try and test for are:
283 * + There can never be two non-NIL entries with the same { Port, Node } WWN
286 * + There can never be two non-NIL entries with the same handle.
290 * This is the handle that the firmware needs in order for us to
291 * send commands to the device. For pre-24XX cards, this would be
297 * PRLI word 0 contains the Establish Image Pair bit, which is
298 * important for knowing when to reset the CRN.
300 * PRLI word 3 parameters contains role as well as other things.
302 * The state is the current state of this entry.
304 * The is_target is the current state of target on this port.
306 * The is_initiator is the current state of initiator on this port.
308 * Portid is obvious, as are node && port WWNs. The new_role and
309 * new_portid is for when we are pending a change.
