From: Chad Dupuis <chad.dupuis@qlogic.com>

If the firmware cannot find the command specified then return SUCCESS to the
error handler so as not to needlessly escalate.  Also cleanup the resources for
the command since we cannot expect the original command to returned in
interrupt context.

  To: jbottomley; +Cc: giridhar.malavali, saurav.kashyap, andrew.vasquez, linux-scsi

From: Joe Carnuccio <joe.carnuccio@qlogic.com>

For ISP27xx use the request/response queue index shadow registers
to avoid directly access them on the PCI bus.

From: Quinn Tran <quinn.tran@qlogic.com>

Add support for T10-Dif for Target Mode to qla driver.
The driver will look for firmware attribute that support
this feature.  When the feature is present, the capabilities
will be report to TCM layer.

Add CTIO CRC2 iocb to build T10-Dif commands.
Add support routines to process good & error cases.

From: Quinn Tran <quinn.tran@qlogic.com>

Fix double free problem within qla2xxx driver where
current code prematurely free qla_tgt_cmd while firmware
still has the command.  When firmware release the command
after abort, the code attempt a second free as part of
command completion processing.

When TCM start the free process, NULL pointer was hit.

Hi Saurav + Quinn,

Just curious if this fix needs to be CC'ed to stable as well, or if it's
something that is only triggered with the preceding T10 DIF support
patch in place..?

Nicholas,

At this point we can forgo this patch to stable tree.  There are
additional tweaks in this path during testing.  We will update the stable
tree with new findings.

Thanks.

Regards,
Quinn Tran

From: Chad Dupuis <chad.dupuis@qlogic.com>

Attempting to do any logins from the SCSI reset handler can lead to a deadlock
scenario if a rport times out and the FC transport layer.  Move doing any port
logins to the DPC thread so as not to impede the progress of the SCSI error
handler thread and avoid deadlock situations.

From: Chad Dupuis <chad.dupuis@qlogic.com>

This can block progress of the SCSI error handler thread and cause long I/O
outages.  Instead just fail immediately if another reset is going on or we are
accessing flash memory.
