1458  * DDI_DETACH are:
1459  *	+	Grab the port driver mutex, check if the unsolicited
1460  *		callback is currently under processing. If true, fail
1461  *		the DDI_DETACH request by printing a message; If false
1462  *		mark the DDI_DETACH as under progress, so that any
1463  *		further unsolicited callbacks get bounced.
1464  *	+	Perform PRLO/LOGO if necessary, cleanup all the data
1465  *		structures.
1466  *	+	Get the job_handler thread to gracefully exit.
1467  *	+	Unregister callbacks with the FCA port.
1468  *	+	Now that some peace is found, notify all the ULPs of
1469  *		DDI_DETACH request (using ulp_port_detach entry point)
1470  *	+	Free all mutexes, semaphores, conditional variables.
1471  *	+	Free the soft state, return success.
1472  *
1473  * Important considerations:
1474  *		Port driver de-registers state change and unsolicited
1475  *		callbacks before taking up the task of notifying ULPs
1476  *		and performing PRLO and LOGOs.
1477  *
1478  *		A port may go offline at the time PRLO/LOGO is being
1479  *		requested. It is expected of all FCA drivers to fail
1480  *		such requests either immediately with a FC_OFFLINE
1481  *		return code to fc_fca_transport() or return the packet
1482  *		asynchronously with pkt state set to FC_PKT_PORT_OFFLINE

10843 	 * 2. Before mutex is released, a copy of it is stored in rscn_count.
10844 	 * 3. The count is passed to job thread as JOB_UNSOL_REQUEST (below)
10845 	 *    by overloading the job_cb_arg to pass the rscn_count
10846 	 * 4. When one of the routines processing the RSCN picks it up (ex:
10847 	 *    fp_validate_rscn_page()), it passes this count in the map
10848 	 *    structure (as part of the map_rscn_info structure member) to the
10849 	 *    ULPs.
10850 	 * 5. When ULPs make calls back to the transport (example interfaces for
10851 	 *    this are fc_ulp_transport(), fc_ulp_login(), fc_issue_els()), they
10852 	 *    can now pass back this count as part of the fc_packet's
10853 	 *    pkt_ulp_rscn_count member. fcp does this currently.
10854 	 * 6. When transport gets a call to transport a command on the wire, it
10855 	 *    will check to see if there is a valid pkt_ulp_rsvd1 field in the
10856 	 *    fc_packet. If there is, it will match that info with the current
10857 	 *    rscn_count on that instance of the port. If they don't match up
10858 	 *    then there was a newer RSCN. The ULP gets back an error code which
10859 	 *    informs it about it - FC_DEVICE_BUSY_NEW_RSCN.
10860 	 * 7. At this point the ULP is free to make up its own mind as to how to
10861 	 *    handle this. Currently, fcp will reset its retry counters and keep
10862 	 *    retrying the operation it was doing in anticipation of getting a
10863 	 *    new state change call back for the new RSCN.

11259  * A Process Logout should be handled by the ULP that established it.  However,
11260  * some devices send a PRLO to trigger a PLOGI followed by a PRLI.  This happens
11261  * when a device implicitly logs out an initiator (for whatever reason) and
11262  * tries to get that initiator to restablish the connection (PLOGI and PRLI).
11263  * The logical thing to do for the device would be to send a LOGO in response
11264  * to any FC4 frame sent by the initiator. Some devices choose, however, to send
11265  * a PRLO instead.
11266  *
11267  * From a Fibre Channel standpoint a PRLO calls for a PRLI. There's no reason to
11268  * think that the Port Login has been lost.  If we follow the Fibre Channel
11269  * protocol to the letter a PRLI should be sent after accepting the PRLO.  If
11270  * the Port Login has also been lost, the remote port will reject the PRLI
11271  * indicating that we must PLOGI first.	 The initiator will then turn around and
11272  * send a PLOGI.  The way Leadville is layered and the way the ULP interface
11273  * is defined doesn't allow this scenario to be followed easily.  If FCP were to
11274  * handle the PRLO and attempt the PRLI, the reject indicating that a PLOGI is
11275  * needed would be received by FCP. FCP would have, then, to tell the transport
11276  * (fp) to PLOGI.  The problem is, the transport would still think the Port
11277  * Login is valid and there is no way for FCP to tell the transport: "PLOGI even
11278  * if you think it's not necessary".  To work around that difficulty, the PRLO
11279  * is treated by the transport as a LOGO.  The downside to it is a Port Login
11280  * may be disrupted (if a PLOGI wasn't actually needed) and another ULP (that
11281  * has nothing to do with the PRLO) may be impacted.  However, this is a
11282  * scenario very unlikely to happen.  As of today the only ULP in Leadville
11283  * using PRLI/PRLOs is FCP.  For a PRLO to disrupt another ULP (that would be
11284  * FCIP), a SCSI target would have to be running FCP and FCIP (which is very
11285  * unlikely).
