When Target port transitions personality from one to another (NVMe <-->

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.

...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.

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.

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.

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

memory. It will pass it to HW.
It is assumed that application will assign a unique SPI value to this SADB

SPI/SADB.

(EDIF). This feature requires an application to act as an authenticator.
Add two new BSG calls:
- QL_VND_SC_APP_START: Application will announce its presence to driver
with this call. Driver will restart all connections to see if remote
device supports security or not.
- QL_VND_SC_APP_STOP: Application announces it is in the process of
exiting. Driver will restart all connections to revert back to
non-secure. Provided the remote device is willing to allow a non-secure
connection.

This is a set of minor fixes and clean ups in the core and various
drivers. The only core change in behaviour is the I/O retry for
spinup notify, but that shouldn't impact anything other than the
failing case.

elx and mpi3mr being new drivers. The major core change is a rework
to drop the status byte handling macros and the old bit shifted
definitions and the rest of the updates are minor fixes.
