[PATCH v6 06/18] nvme: Rapid Path Failure Recovery read controller identify fields

[Daniel Wagner]

> TP8028 Rapid Path Failure added new fields to controller identify
> response. Read CIU (Controller Instance Uniquifier), CIRN (Controller
> Instance Random Number), and CCRL (Cross-Controller Reset Limit) from
> controller identify response. Expose CIU and CIRN as sysfs attributes
> so the values can be used directly by user if needed.

What's the use case for it? This is an public/stable interface,
it needs a justification and documentation

> Also add the nvme_fence_timeout_ms() helper that derives a fencing
> timeout from the controller keep-alive timeout (kato).

There is no user in this patch, introduce it when you use it.
