[PATCH v3 0/9] qla2xxx driver misc features

[Nilesh Javali]

Martin,

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

v3:
- Skip patch "qla2xxx: Observed call trace in smp_processor_id()"
- Change description of patch 1/9
v2:
- Remove extra line from qla_iocb.c
- Fix comment style for qla2xxx_process_purls_pkt()
- Add Reviewed-by tag

Thanks,
Nilesh

[PATCH v3 1/9] qla2xxx: Add Unsolicited LS Request and Response Support for NVMe

[Nilesh Javali]

From: Manish Rangankar <mrangankar@marvell.com>

Introduce infrastructure in the driver to support the processing
of unsolicited LS (Link Service) requests. This will involve the
utilization of a new pass-up of unsolicited FC-NVMe request iocb
interface. Unsolicited requests will be submitted to the NVMe
transport layer through nvme_fc_rcv_ls_req(). Any received LS
responses, which are sent using xmt_ls_rsp(), will be forwarded
to the firmware through the existing Pass-Through IOCB interface,
responsible for sending FC-NVMe Link Service requests and responses.

.. and it now made it to mainline and causes sparse warnings in the
core nvme-fc and lpfc code.

I have posted a fix for this in qla2xxx driver reverting changes done in nvme-fc-driver.h,

[PATCH v3 2/9] qla2xxx: Flush mailbox commands on chip reset

[Nilesh Javali]

From: Quinn Tran <qutran@marvell.com>

Fix race condition between Interrupt thread and Chip reset
thread in trying to flush the same mailbox. With the race
condition, the "ha->mbx_intr_comp" will get an extra complete()
call. The extra complete call create erroneous mailbox timeout
condition when the next mailbox is sent where the mailbox call
does not wait for interrupt to arrive. Instead, it advance
without waiting.

Add lock protection around the check for mailbox completion.

[PATCH v3 3/9] qla2xxx: Fix fw resource tracking

[Nilesh Javali]

From: Quinn Tran <qutran@marvell.com>

The storage was not draining io's and the work load
is not spread out across different CPU's evenly. This led to
FW resource counters getting over run on the busy CPU. This
overrun prevented error recovery from happening in a timely
manner.

By switching the counter to atomic, it allows the count to
be little more accurate to prevent the overrun.

[PATCH v3 5/9] qla2xxx: Error code did not return to upper layer

[Nilesh Javali]

From: Quinn Tran <qutran@marvell.com>

TMF was returned with an error code. The error code was not
preserved to be returned to upper layer. Instead, the error code
from the Marker was returned.

Preserve error code from TMF and return it to upper layer.

[PATCH v3 6/9] qla2xxx: Remove unsupported ql2xenabledif option.

[Nilesh Javali]

From: Manish Rangankar <mrangankar@marvell.com>

User accidently pass module param ql2xenabledif=1, which is unsupported
in driver, but driver still progress and lead to guard tag error during
device discovery.

Remove unsupported ql2xenabledif=1 option and validate the user input.
