Changing a lun's queue depth (/sys/block/sdX/device/queue_depth)
isn't sticky when the device is connected via a QLogic fibre
channel adapter.
The QLogic qla2xxx fibre channel driver dynamically adjusts a
lun's queue depth. If a user has a specific need to limit the
number of commands issued to a lun (say a tape drive, or a shared
raid where the total commands issued to all luns is limited at
the controller level, for example) and writes a limiting value to
/sys/block/sdXX/device/queue_depth, the qla2xxx driver will
silently and gradually increase the queue depth back to the
driver limit of ql2xmaxqdepth. While reducing this value (module
parameter) or increasing the interval between ramp ups
(ql2xqfullrampup) offers the potential for a work around it would
be better to have the option of just disabling the dynamic
adjustment of queue depth.
This patch implements an "off switch" as a module parameter.

As the driver depends on the DPC routine to handle bottom-half
loop resynchronization in order to recover from the issue-lip
request. The issue_lip call is sleeping context capable, so just
issue the reset function there.

Newer ISPs support a mechanism to read and write flash-memory via
the firmware LOAD/DUMP memory mailbox command routines. When
supported, utilizing these mechanisms significantly reduces
overall access times.

- Drop queue-depths across all luns for a given fcport
during TASK_SET_FULL statuses.
- Ramp-up I/Os after throttling.
- Consolidate completion-status handling of CS_QUEUE_FULL with
CS_COMPLETE as ISP24xx firmware no longer reports
CS_QUEUE_FULL.

Early ISP2432 parts have a known hardware issue when coming
out of a D3 hot state. This issue can result in a hung PCIe
link. Recent firmwares contain a workaround whereby the
stop-firmware mailbox command prevents the ISP from entering
the D3 hot state.
In order to ensure that the workaround succeeded the driver
must verify that the stop-firmware mailbox command completes
successfully. In the event of a failure, the driver
attempts a shutdown-retry after resetting the ISP and
re-executing firmware.
