10911 10896 * 2. Before mutex is released, a copy of it is stored in rscn_count.
10912 10897 * 3. The count is passed to job thread as JOB_UNSOL_REQUEST (below)
10913 10898 * by overloading the job_cb_arg to pass the rscn_count
10914 10899 * 4. When one of the routines processing the RSCN picks it up (ex:
10915 10900 * fp_validate_rscn_page()), it passes this count in the map
10916 10901 * structure (as part of the map_rscn_info structure member) to the
10917 10902 * ULPs.
10918 10903 * 5. When ULPs make calls back to the transport (example interfaces for
10919 10904 * this are fc_ulp_transport(), fc_ulp_login(), fc_issue_els()), they
10920 10905 * can now pass back this count as part of the fc_packet's
10921 10906 * pkt_ulp_rscn_count member. fcp does this currently.
10922 10907 * 6. When transport gets a call to transport a command on the wire, it
10923 10908 * will check to see if there is a valid pkt_ulp_rsvd1 field in the
10924 10909 * fc_packet. If there is, it will match that info with the current
10925 10910 * rscn_count on that instance of the port. If they don't match up
10926 10911 * then there was a newer RSCN. The ULP gets back an error code which
10927 10912 * informs it about it - FC_DEVICE_BUSY_NEW_RSCN.
10928 10913 * 7. At this point the ULP is free to make up its own mind as to how to
10929 10914 * handle this. Currently, fcp will reset its retry counters and keep
10930 10915 * retrying the operation it was doing in anticipation of getting a
10931 10916 * new state change call back for the new RSCN.

11327 11312 * A Process Logout should be handled by the ULP that established it. However,
11328 11313 * some devices send a PRLO to trigger a PLOGI followed by a PRLI. This happens
11329 11314 * when a device implicitly logs out an initiator (for whatever reason) and
11330 11315 * tries to get that initiator to restablish the connection (PLOGI and PRLI).
11331 11316 * The logical thing to do for the device would be to send a LOGO in response
11332 11317 * to any FC4 frame sent by the initiator. Some devices choose, however, to send
11333 11318 * a PRLO instead.
11334 11319 *
11335 11320 * From a Fibre Channel standpoint a PRLO calls for a PRLI. There's no reason to
11336 11321 * think that the Port Login has been lost. If we follow the Fibre Channel
11337 11322 * protocol to the letter a PRLI should be sent after accepting the PRLO. If
11338 11323 * the Port Login has also been lost, the remote port will reject the PRLI
11339 11324 * indicating that we must PLOGI first. The initiator will then turn around and
11340 11325 * send a PLOGI. The way Leadville is layered and the way the ULP interface
11341 11326 * is defined doesn't allow this scenario to be followed easily. If FCP were to
11342 11327 * handle the PRLO and attempt the PRLI, the reject indicating that a PLOGI is
11343 11328 * needed would be received by FCP. FCP would have, then, to tell the transport
11344 11329 * (fp) to PLOGI. The problem is, the transport would still think the Port
11345 11330 * Login is valid and there is no way for FCP to tell the transport: "PLOGI even
11346 11331 * if you think it's not necessary". To work around that difficulty, the PRLO
11347 11332 * is treated by the transport as a LOGO. The downside to it is a Port Login
11348 11333 * may be disrupted (if a PLOGI wasn't actually needed) and another ULP (that
11349 11334 * has nothing to do with the PRLO) may be impacted. However, this is a
11350 11335 * scenario very unlikely to happen. As of today the only ULP in Leadville
11351 11336 * using PRLI/PRLOs is FCP. For a PRLO to disrupt another ULP (that would be
11352 11337 * FCIP), a SCSI target would have to be running FCP and FCIP (which is very
11353 11338 * unlikely).
