Complete the enablement of the cm framework feature in the adapter. Perform
the following:

 - Detect the presence of the congestion management framework feature.

When the cm framework is present:

 - Issue the SET_FEATURE command to enable the feature.

 - Register the cm statistics buffer with the adapter.

 - Read the cm enablement buffer to determine the cm framework state for cm
   management.

When cm management is enabled:

 - Monitor all FPIN and congestion signalling events, incrementing
   counters.

 - Regularly sync with the adapter to communicate congestion events and to
   receive an rx request limit.

 - Monitor requests for rx data and ensure that no more than the
   adapter prescribed limit is issued on the link. If the limit is
   exceeded, SCSI and/or NVMe traffic is temporarily suspended.

 - Maintain the minute, hourly, daily statistics buffer.

 - Monitor for congestion enablement change events, causing a reread of the
   enablement buffer and acting on any change in enablement.

And:

 - Add teardown logic, including buffer deregistration, on adapter
   detachment or reset.

MIB support is currently limited to detecting support in the adapter and
ensuring FDMI support is enabled if present.  For the new framework MIB
support also requires active enablement of support via the SET_FEATURES
command with the firmware.

Rework the MIB detection and enablement for the following:

 - Move detection away from the get_sli4_parameters routine, and into the
   hba_setup path. get_sli4_parameters is only called once at attachment
   while hba_setup is called as part of any SLI port reset path. This
   ensures detection after firmware download.

 - Update SET_FEATURES mbx command for the MIB enablement feature and add
   support for the feature.

 - Create the cmf_setup routine to encapsulate the detection of MIB support
   and perform the enablement of the MIB support feature.

The lpfc_sli4_nvmet_xri_aborted() routine takes out the abts_buf_list_lock
and traverses the buffer contexts to match the xri. Upon match, it then
takes the context lock before potentially removing the context from the
associated buffer list. This violates the lock hierarchy used elsewhere in
the driver of locking context, then the abts_buf_list_lock - thus a
possible deadlock.

Resolve by: after matching, release the abts_buf_list_lock, then take the
context lock, and if to be deleted from the list, retake the
abts_buf_list_lock, maintaining lock hierarchy. This matches same list lock
hierarchy as elsewhere in the driver

When a node moves to NPR state due to a device recovery event, the
nlp_fc4_types in the node are cleared. An ADISC received for a node in the
NPR state triggers an ADISC. Without fc4 types being known, the calls to
register with the transport are no-op'd, thus no additional references are
placed on the node by transport re-registrations. A subsequent RSCN could
trigger another unregister request, which will decrement the reference
counts, leading to the ref count hitting zero and the node being freed
while futher discovery on the node is being attempted by the RSCN event
handling.

Fix by skipping the trigger of an ADISC when in NPR state. The normal ADISC
process will kick off in the regular discovery path after receiving a
response from name server.

During RSCN storms, some instances of LIP on SLI-3 adapters lead to a
situation where FLOGIs keep failing with firmware indicating an illegal
command error code.  This situation was preceded by an ADISC completion
that was processed while the link was down. This path on SLI-3 performs a
CLEAR_LA and attempts to activate a VPI with REG_VPI.  Later, as the FLOGI
completes, it's no longer in sync with the VPI state.  In SLI-3 it is
illegal to have an active VPI during FLOGI.

Resolve by circumventing the SLI-3 path that performs the CLEAR_LA and
REG_VPI. The path will be taken after the FLOGI after the next Link Up.

In the PLOGI and ADISC completion handling, the device removal event could
be skipped during some link errors. This could leave a stale node in UNUSED
state.  Driver unload would hang for a long time waiting for this node to
be freed.

Resolve by taking the following steps:

 - Always post ADISC completion events to discovery state machine upon
   ADISC completion.

 - In case of a completion error for PLOGI/ADISC, ensure that init refcount
   is dropped if not registered with transport.

On an RSCN event, the nodes specified in RSCN payload and in MAPPED state
are moved to NPR state in order to revalidate the login. This triggers an
immediate unregister from SCSI/NVMe backend. The assumption is that the
node may be missing. The re-registration with the backend happens after
either relogin (PLOGI/PRLI; if ADISC is disabled or login truly lost) or
when ADISC completes successfully (rediscover with ADISC enabled).

However, the NVMe-FC standard provides for an RSCN to be triggered when
the remote port supports a discovery controller and there was a change
of discovery log content. As the remote port typically also supports
storage subsystems, this unregister causes all storage controller
connections to fail and require reconnect.

Correct by reworking the code to ensure that the unregistration only occurs
when a login state is truly terminated, thereby leaving the NVMe storage
controllers in place.

The changes made are:

 - Retain node state in ADISC_ISSUE when scheduling ADISC ELS retry.

 - Do not clear wwpn/wwnn values upon ADISC failure.

 - Move MAPPED nodes to NPR during RSCN processing, but do not unregister
   with transport.  On GIDFT completion, identify missing nodes (not marked
   NLP_NPR_2B_DISC) and unregister them.

 - Perform unregistration for nodes that will go through ADISC processing
   if ADISC completion fails.

 - Successful ADISC completion will move node back to MAPPED state.

Integration with VMID patches resulted in a build error when
CONFIG_DEBUG_FS is disabled and driver option CONFIG_SCSI_LPFC_DEBUG_FS is
disabled.

It results in an undefined variable:
lpfc_scsi:5595:3: error: 'uuid' undeclared (first use in this function); did you mean 'upid'?
