[PATCH v3 0/3] qla2xxx: Updates for the driver

[Nilesh Javali]

Hi Martin,

Please apply the qla2xxx driver bug fixes to the scsi tree at your earliest
convenience.

v1->v2:
- PATCH 1/3 - Removed unused variables, count and fw_dump_mpi, from func qla27xx_fwdump
qla_tmpl.c

v2->v3:
- PATCH 0/3 - Added Changelog and base-commit
- PATCH 1/3 - Fixed warning reported by kbuild test robot and added Reviewed-by
tag
- PATCH 2/3 - Added Reviewed-by tag
- PATCH 3/3 - Added Reviewed-by tag

Thanks,
Nilesh

[PATCH v3 1/3] qla2xxx: Fix MPI failure AEN (8200) handling.

[Nilesh Javali]

From: Arun Easi <aeasi@marvell.com>

Today, upon an MPI failure AEN, on top of collecting an MPI dump, a
regular firmware dump is also taken and the chip reset. This is
disruptive to IOs and not required. So, make the firmware dump
collection, followed by chip reset optional (not done by default).

Firmware dump buffer and MPI dump buffer are independent of each
other with this change and each can have dump that was taken at two
different times for two different issues. The MPI dump is saved in a
separate buffer and is retrieved differently from firmware dump.

To collect full dump on MPI failure AEN, a module parameter is
introduced:
    ql2xfulldump_on_mpifail (default: 0)

[PATCH v3 2/3] qla2xxx: Fix hang when issuing nvme disconnect-all in NPIV.

[Nilesh Javali]

From: Arun Easi <aeasi@marvell.com>

In NPIV environment, a NPIV host may use a queue pair created
by base host or other NPIVs, so the check for a queue pair
created by this NPIV is not correct, and can cause an abort
to fail, which in turn means the NVME command not returned.
This leads to hang in nvme_fc layer in nvme_fc_delete_association()
which waits for all I/Os to be returned, which is seen as hang
in the application.

[PATCH v3 3/3] qla2xxx: delete all sessions before unregister local nvme port

[Nilesh Javali]

From: Quinn Tran <qutran@marvell.com>

Delete all sessions before unregistering local nvme port.  This
allows nvme layer to decrement all active rport count down to zero.
Once the count is down to zero, nvme would call qla to continue with
the npiv port deletion.
