Kernel crashes when accessing port_speed sysfs file. The issue happens on
a CNA when the local array was accessed beyond bounds. Fix this by changing
the lookup.

Authentication application may be running and in the past tried to probe
driver (app_start) but was unsuccessful. This could be due to the bsg layer
not being ready to service the request. On a successful link up, driver
will use the netlink Link Up event to notify the app to retry the app_start
call.
In another case, app does not poll for new NPIV host. This link up event
would notify app of the presence of a new SCSI host.

When Target port transitions personality from one to another (NVMe <-->
FCP), there could be some overlap of the two where one layer is going down
while the other layer is coming up. This overlap can cause temporary I/O
error. Detect those errors/transitions and recover from them. Triggers
session tear down and allow relogin to re-drive the connection under the
following conditions:
- NVMe command error
- On PRLO + N2N (rida format 2)

For target port that register itself as both FCP + NVMe, initiator driver
will try to login one mode at a time. If the last mode did not succeed,
then driver will try the other mode.
When error is encountered, current code only flip to other mode one time
(NVMe->FCP) and remain on the last mode. Driver wrongly assumed target
port does not support PRLI NVMe, instead it was not ready to receive PRLI.
This patch will alternate back and forth on every PRLI failure until login
retry count has depleted or it is succeeded.

The abort callback gets called only when it gets posted to firmware. The
refcounting is done properly in the callback. On internal errors, the
callback is not invoked leading to a hung I/O. Fix this by having separate
error code when command gets returned from firmware.

...when device side port resets were done.
Abort threads were getting out without processing due to the "deleted"
flag check. The delete thread, meanwhile, could not proceed with a
logout (that would have cleared out pending requests) as the logout IOCB
work was not progressing. It appears like the hung qlt_free_session_done()
thread is causing the ha->wq works on hold. The qlt_free_session_done()
was hung waiting for nvme_fc_unregister_remoteport() + localport_delete cb
to be complete, which would only happen when all I/Os are released.
Fix this by allowing abort to progress until device delete is completely
done. This should make the qlt_free_session_done() proceed without hang and
thus clear up the deadlock.

The first invocation of function find_first_zero_bit will return 0 and
queue_id gets set to 0.
An index of queue_pair_map also gets set to 0.
qpair_id = find_first_zero_bit(ha->qpair_qid_map, ha->max_qpairs);
set_bit(qpair_id, ha->qpair_qid_map);
ha->queue_pair_map[qpair_id] = qpair;
In the alloc_queue callback driver checks the map, if queue is already
allocated:
ha->queue_pair_map[qidx]
This works fine as long as max_qpairs is greater than nvme_max_hw_queues(8)
since the size of the queue_pair_map is equal to max_qpair. In case nr_cpus
is less than 8, max_qpairs is less than 8. This creates wrong value
returned as qpair.

The MSI-X and MSI calls fails in kdump kernel. Because of this
qla2xxx_create_qpair() fails leading to .create_queue callback failure.
The fix is to return existing qpair instead of allocating new one and
allocate a single hw queue.

Some FC adapters from Marvell offer the ability to encrypt data in flight
(EDIF). This feature requires an application to act as an authenticator.
During runtime, driver and authentication application need to stay in sync
in terms of: Session being down|up, arrival of new authentication
message (AUTH ELS) and SADB update completion.
These events are queued up as doorbell to the authentication
application. Application would read this doorbell on regular basis to stay
up to date. Each SCSI host would have a separate doorbell queue.
The doorbell interface can daisy chain a list of events for each read. Each
event contains an event code + hint to help application steer the next
course of action.

Some FC adapters from Marvell offer the ability to encrypt data in flight
(EDIF). This feature requires an application to act as an authenticator.
There is no FC switch scan service that can indicate whether a device is
secure or non-secure.
In order to detect whether the remote port supports encrypted operation,
driver must first do a PLOGI with the remote device. On completion of the
PLOGI, driver will query firmware to see if the device supports secure
login. To do that, driver + firmware must advertise the security bit via
PLOGI's service parameter. The remote device shall respond using the same
service parameter whether it supports it or not.

On completion of the authentication process, the authentication application
will notify driver on whether it is successful or not.
In case of success, application will use the QL_VND_SC_AUTH_OK BSG call to
tell driver to proceed to the PRLI phase.
In case of failure, application will use the QL_VND_SC_AUTH_FAIL bsg call
to tell driver to tear down the connection and retry. In the case where an
existing session is active, the re-key process can fail. The session tear
down ensures data is not further compromised.

Some FC adapters from Marvell offer the ability to encrypt data in flight
(EDIF). This feature requires an application to act as an authenticator.
As part of the authentication process, the authentication application will
generate a SADB entry (Security Association/SA, key, SPI value, etc). This
SADB is then passed to driver to be programmed into hardware. There will be
a pair of SADB's (Tx and Rx) for each connection.
After some period, the application can choose to change the key. At that
time, a new set of SADB pair is given to driver. The old set of SADB will
be deleted.
Add a new bsg call (QL_VND_SC_SA_UPDATE) to allow application to allow
adding or deleting SADB entries. Driver will not keep the key in
memory. It will pass it to HW.
It is assumed that application will assign a unique SPI value to this SADB
(SA + key). Driver + hardware will assign a handle to track this unique
SPI/SADB.

Once authentication messages sent from a remote device have arrived, each

The FC frame header will be stripped, leaving behind the AUTH ELS payload.
It is up to the application to strip the AUTH ELS header to get to the
actual authentication message.

If a message was received, application is required to reply with either a
LS_ACC or LS_RJT complete the exchange using the same interface. Otherwise,
