1462  *              further unsolicited callbacks get bounced.
1463  *      +       Perform PRLO/LOGO if necessary, cleanup all the data
1464  *              structures.
1465  *      +       Get the job_handler thread to gracefully exit.
1466  *      +       Unregister callbacks with the FCA port.
1467  *      +       Now that some peace is found, notify all the ULPs of
1468  *              DDI_DETACH request (using ulp_port_detach entry point)
1469  *      +       Free all mutexes, semaphores, conditional variables.

1942  * are becoming more and more powerful on huge servers.  So it
1943  * is desirable to have a framework support to reserve a fragment
1944  * of DVMA. So until this is fixed the correct way, the suffering
1945  * is huge whenever a LIP happens at a time DVMA resources are
1946  * drained out completely - So an attempt needs to be made to
1947  * KM_SLEEP while requesting for these resources, hoping that
1948  * the requests won't hang forever.
1949  *
1950  * The fc_remote_port_t argument is stored into the pkt_pd field in the
1951  * fc_packet_t struct prior to the fc_ulp_init_packet() call.  This
1952  * ensures that the pd_ref_count for the fc_remote_port_t is valid.
1953  * If there is no fc_remote_port_t associated with the fc_packet_t, then
1954  * fp_alloc_pkt() must be called with pd set to NULL.
1955  *
1956  * fp/fctl will resue fp_cmd_t somewhere, and change pkt_cmdlen/rsplen,
1957  * actually, it's a design fault. But there's no problem for physical
1958  * FCAs. But it will cause memory leak or panic for virtual FCAs like fcoei.
1959  *
1960  * For FCAs that don't support DMA, such as fcoei, we will use
1961  * pkt_fctl_rsvd1/rsvd2 to keep the real cmd_len/resp_len.

5836  *      In a point to point topology with an N_Port, during Fabric Login,

5839  *      trigger an unsolicited PLOGI from an N_Port. The Unsolicited
5840  *      PLOGI creates the device handles.
5841  *
5842  *      Assuming that the host port WWN is greater than the other N_Port
5843  *      WWN, then we become the master (be aware that this isn't the word

10910          * 1. fp_unsol_cb() gets an RSCN and updates fp_rscn_count.
10911          * 2. Before mutex is released, a copy of it is stored in rscn_count.
10912          * 3. The count is passed to job thread as JOB_UNSOL_REQUEST (below)
10913          *    by overloading the job_cb_arg to pass the rscn_count
10914          * 4. When one of the routines processing the RSCN picks it up (ex:
10915          *    fp_validate_rscn_page()), it passes this count in the map
10916          *    structure (as part of the map_rscn_info structure member) to the
10917          *    ULPs.
10918          * 5. When ULPs make calls back to the transport (example interfaces for
10919          *    this are fc_ulp_transport(), fc_ulp_login(), fc_issue_els()), they
10920          *    can now pass back this count as part of the fc_packet's
10921          *    pkt_ulp_rscn_count member. fcp does this currently.
10922          * 6. When transport gets a call to transport a command on the wire, it
10923          *    will check to see if there is a valid pkt_ulp_rsvd1 field in the
10924          *    fc_packet. If there is, it will match that info with the current
10925          *    rscn_count on that instance of the port. If they don't match up
10926          *    then there was a newer RSCN. The ULP gets back an error code which
10927          *    informs it about it - FC_DEVICE_BUSY_NEW_RSCN.
10928          * 7. At this point the ULP is free to make up its own mind as to how to
10929          *    handle this. Currently, fcp will reset its retry counters and keep
10930          *    retrying the operation it was doing in anticipation of getting a
10931          *    new state change call back for the new RSCN.

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