331 * FC Port Database entry.
333 * It has a handle that the f/w uses to address commands to a device.
334 * This handle's value may be assigned by the firmware (e.g., for local loop
335 * devices) or by the driver (e.g., for fabric devices).
337 * It has a state. If the state if VALID, that means that we've logged into
340 * Local loop devices the firmware automatically performs PLOGI on for us
341 * (which is why that handle is imposed upon us). Fabric devices we assign
342 * a handle to and perform the PLOGI on.
344 * When a PORT DATABASE CHANGED asynchronous event occurs, we mark all VALID
345 * entries as PROBATIONAL. This allows us, if policy says to, just keep track
346 * of devices whose handles change but are otherwise the same device (and
347 * thus keep 'target' constant).
349 * In any case, we search all possible local loop handles. For each one that
350 * has a port database entity returned, we search for any PROBATIONAL entry
351 * that matches it and update as appropriate. Otherwise, as a new entry, we
352 * find room for it in the Port Database. We *try* and use the handle as the
353 * index to put it into the Database, but that's just an optimization. We mark
354 * the entry VALID and make sure that the target index is updated and correct.
356 * When we get done searching the local loop, we then search similarily for
357 * a list of devices we've gotten from the fabric name controller (if we're
358 * on a fabric). VALID marking is also done similarily.
360 * When all of this is done, we can march through the database and clean up
361 * any entry that is still PROBATIONAL (these represent devices which have
362 * departed). Then we're done and can resume normal operations.
364 * Negative invariants that we try and test for are:
366 * + There can never be two non-NIL entries with the same { Port, Node } WWN
369 * + There can never be two non-NIL entries with the same handle.
373 * This is the handle that the firmware needs in order for us to
374 * send commands to the device. For pre-24XX cards, this would be
380 * PRLI word 3 parameters contains role as well as other things.
382 * The state is the current state of this entry.
384 * The is_target is the current state of target on this port.
386 * The is_initiator is the current state of initiator on this port.
388 * Portid is obvious, as are node && port WWNs. The new_role and
389 * new_portid is for when we are pending a change.

654 * For each channel, the outer layers should know what role that channel
655 * will take: ISP_ROLE_NONE, ISP_ROLE_INITIATOR, ISP_ROLE_TARGET,
658 * If you set ISP_ROLE_NONE, the cards will be reset, new firmware loaded,
659 * NVRAM read, and defaults set, but any further initialization (e.g.
660 * INITIALIZE CONTROL BLOCK commands for 2X00 cards) won't be done.
662 * If INITIATOR MODE isn't set, attempts to run commands will be stopped
663 * at isp_start and completed with the equivalent of SELECTION TIMEOUT.
665 * If TARGET MODE is set, it doesn't mean that the rest of target mode support
