From: Arun Easi <aeasi@marvell.com>

Driver was using a lower value for dev_loss_tmo making it more prone to
I/O failures during remote port toggle testing. Set dev_loss_tmo to zero
during remote port registration to allow nvme-fc default dev_loss_tmo to
be used, which is higher than what driver was using.

From: Arun Easi <aeasi@marvell.com>

FCP-4 (referred FCP-4 rev-2b) identifies the earlier known "retry delay
timer" field as "status qualifier", which is described in SAM-5 and
later specs. This fix makes appropriate driver side modifications to
honor the new definition. The SAM document referred was SAM-6 rev-5.

delete finishes.

From: Quinn Tran <qutran@marvell.com>

This patch tracks number of IOCB resources used in the IO
fast path. If the number of used IOCBs reach a high water
limit, driver would return the IO as busy and let upper layer
retry. This prevents over subscription of IOCB resources where
any future error recovery command is unable to cut through.
Enable IOCB throttling by default.

From: Saurav Kashyap <skashyap@marvell.com>

BIT_13 of extended FW attribute informs about NVMe-2 support.
Set BIT_15 of special feature control block for enabling SLER in FW.
Set bit 8 (SLER supported) to 1 for the service parameter information
when sending NVMe PRLI request.
Set BIT_14 of special feature control block for enabling
PI Control in FW.
Driver should set bit 9 (PI Control supported) to 1 for the service
parameter information when sending NVMe PRLI request.
Set BIT_13 for NVMe Async events.

Please use the block layer reserved tag mechanism instead of adding
a mechanism that is (a) racy and (b) triggers cache line ping-pong.

Thanks,

QT: The Block layer reserve tag does fit resource we're tracking.  The reserve tag is per command.  The IOCB resource is adapter specific behind  all commands.
