|
|
* 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.

|
*
|
|
* DEFAULT_ROLE(ispsoftc_t *, int) Get Default Role for a channel
|
|
* DEFAULT_LOOPID(ispsoftc_t *, int) Default FC Loop ID
|
|
*
|
|
* These establish reasonable defaults for each platform.
|
|

|
* to be used should NVRAM not be readable.
|

*
|
|
* DEFAULT_NODEWWN(ispsoftc_t *, chan) Default FC Node WWN to use
|
|
* DEFAULT_PORTWWN(ispsoftc_t *, chan) Default FC Port WWN to use
|
|
*
|
|
* These defines are hooks to allow the setting of node and
|
|
* port WWNs when NVRAM cannot be read or is to be overriden.
|
|
*
|
|
* ACTIVE_NODEWWN(ispsoftc_t *, chan) FC Node WWN to use
|
|
* ACTIVE_PORTWWN(ispsoftc_t *, chan) FC Port WWN to use
|
|
*
|
|
* After NVRAM is read, these will be invoked to get the
|
|
* node and port WWNs that will actually be used for this
|
|
* channel.
