net: devlink: sync flash and dev info commands
Purpose of this patchset is to introduce consistency between two devlink
commands:
devlink dev info
Shows versions of running default flash target and components.
devlink dev flash
Flashes default flash target or component name (if specified
on cmdline).
Currently it is up to the driver what versions to expose and what flash
update component names to accept. This is inconsistent. Thankfully, only
netdevsim currently using components so it is still time
to sanitize this.
This patchset makes sure, that devlink.c calls into driver for
component flash update only in case the driver exposes the same version
name.
Example:
$ devlink dev info
netdevsim/netdevsim10:
driver netdevsim
versions:
running:
fw.mgmt 10.20.30
stored:
fw.mgmt 10.20.30
$ devlink dev flash netdevsim/netdevsim10 file somefile.bin
[fw.mgmt] Preparing to flash
[fw.mgmt] Flashing 100%
[fw.mgmt] Flash select
[fw.mgmt] Flashing done
$ devlink dev flash netdevsim/netdevsim10 file somefile.bin component fw.mgmt
[fw.mgmt] Preparing to flash
[fw.mgmt] Flashing 100%
[fw.mgmt] Flash select
[fw.mgmt] Flashing done
$ devlink dev flash netdevsim/netdevsim10 file somefile.bin component dummy
Error: selected component is not supported by this device.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
