because VCCQ/VCCQ2 can be changed to low-power mode even if VCC stays on
while the device is not in active power mode.

In commit 05c6c029a44d ("scsi: pm80xx: Increase number of supported
queues"), support for 80xx chip was improved by enabling multiple HW
queues.
In this, like other SCSI MQ HBA drivers at the time, the HW queues were not
exposed to upper layer, and instead the driver managed the queues
internally.
However, this management duplicates blk-mq code. In addition, the HW queue
management is sub-optimal for a system where the number of CPUs exceeds the
HW queues - this is because queues are selected in a round-robin fashion,
when it would be better to make adjacent CPUs submit on the same queue. And
finally, the affinity of the completion queue interrupts is not set to
mirror the cpu<->HQ queue mapping, which is suboptimal.
As such, for when MSIX is supported, expose HW queues to upper layer. We
always use queue index #0 for "internal" commands, i.e. anything which does
not come from the block layer, so omit this from the affinity spreading.

User experience slow recovery when target device went through a stop/start
of the authentication application (app_stop/app_start).
Between the period of app_stop and app_start on the target device, target
device choose to send ELS Reject for any receive AUTH ELS command. At this
time, authentication application does not do ELS reject if it encounters
error.
Therefore, AUTH ELS reject signify authentication application is not
running. If driver passes up the AUTH ELS Reject to the authentication
application, then it would result in authentication application
retrying/resending the same AUTH ELS command again + delay.
As a work around, driver should trigger a session tear down where it tells
the local authentication application to also tear down. At the next
relogin, both sides are then synchronized.

knows to tear down its session. Terminate and clean up the AUTH ELS
exchange followed by a passthrough LOGO.
