Jakub Kicinski says: ==================== devlink: add the ability to update device flash This series is the second step to allow trouble shooting and recovering devices in bad state without the use of netdevs as handles. We can already query FW versions over devlink, now we add the ability to update the FW. This will allow drivers to implement some from of "limp-mode" where the device can't really be used for networking and hence has no netdev, but we can interrogate it over devlink and fix the broken FW. Small but nice advantage of devlink is that it only holds the devlink instance lock during flashing, unlike ethtool which holds rtnl_lock(). ==================== Signed-off-by: David S.

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.
