8777e4314d scsi: qla2xxx: Migrate NVME N2N handling into state machine
This patch fixes regression introduced for the N2N support for FC-NVMe. For
FC-NVMe with N2N connection, instead of FW initiating the Login, Driver
starts Login process.  This patch migrates that new process from a
standalone path into existing session management state machine. With this
state change now driver will not wait for pull NPort ID from FW.

9cd883f07a scsi: qla2xxx: Fix session cleanup for N2N
When connection type is N_Port to N_Port (point-to-point), there
is a possibilty where initiator will not send PLOGI request and
will directly send PRLI. In N2N connection the port has higher
port name sends the PLOGI but not allow to send PRLI if is a
target mode. Only initiator is allowed to send PRLI.

Current driver code deletes old session when it receives PLOGI
request. If we will not receive PLOGI request then we will not
delete old session and create new session. Add check for N2N
with PRLI receive only and trigger cleanup. For this case, the
cleanup requires individual cmd abort instead of using implicit
logout as a broad stroke flush.

a5d42f4cff scsi: qla2xxx: Add FC-NVMe port discovery and PRLI handling
Added logic to change the login process into an optional PRIL step for
FC-NVMe ports as a separate operation, such that we can change type to
0x28 (NVMe).

Currently, the driver performs the PLOGI/PRLI together as one operation,
but if the discovered port is an NVMe port then we first issue the PLOGI
and then we issue the PRLI. Also, the fabric discovery logic was changed
to mark each discovered FC NVMe port, so that we can register them with
the FC-NVMe transport later.

41dc529a46 qla2xxx: Improve RSCN handling in driver
Current code blindly does State Change Registration when
the link is up. Move SCR behind fabric scan, so that arbitrated
loop scan would not get erroneous error message.

Some of the other improvements are as follows

- Add session deletion for TPRLO and send acknowledgment for TPRLO.
- Enable FW option to move ABTS, RIDA & PUREX from RSPQ to ATIOQ.
- Save NPort ID early in link init.
- Move ABTS & RIDA to ATIOQ helps in keeping command ordering and
  link up sequence ordering.
- Save Nport ID and update VP map so that SCSI CMD/ATIO won't be dropped.
- fcport alloc does the initializes memory to zero. Remove memset to
  zero since It might corrupt link list.
- Turn off Registration for State Change MB in loop mode.

726b854870 qla2xxx: Add framework for async fabric discovery
Currently code performs a full scan of the fabric for
every RSCN. Its an expensive process in a noisy large SAN.

This patch optimizes expensive fabric discovery process by
scanning switch for the affected port when RSCN is received.

Currently Initiator Mode code makes login/logout decision without
knowledge of target mode. This causes driver and firmware to go
out-of-sync. This framework synchronizes both initiator mode
personality and target mode personality in making login/logout
decision.

This patch adds following capabilities in the driver

- Send Notification Acknowledgement asynchronously.
- Update session/fcport state asynchronously.
- Create a session or fcport struct asynchronously.
- Send GNL asynchronously. The command will ask FW to
  provide a list of FC Port entries FW knows about.
- Send GPDB asynchronously. The command will ask FW to
  provide detail data of an FC Port FW knows about or
  perform ADISC to verify the state of the session.
- Send GPNID asynchronously. The command will ask switch
  to provide WWPN for provided NPort ID.
- Send GPSC asynchronously. The command will ask switch
  to provide registered port speed for provided WWPN.
- Send GIDPN asynchronously. The command will ask the
  switch to provide Nport ID for provided WWPN.
- In driver unload path, schedule all session for deletion
  and wait for deletion to complete before allowing driver
  unload to proceed.

cbc8eb67da [SCSI] qla2xxx: Fallback to 'golden-firmware' operation on supported ISPs.
In case the onboard firmware is unable to be read or loaded for
operation, attempt to fallback to a limited-operational firmware
image stored in a different flash region.  This will allow a user
to reflash and correct a board with proper operational firmware.
