Michal Kubecek says: ==================== ethtool: fail with error if request has unknown flags Jakub Kicinski pointed out that if unrecognized flags are set in netlink header request, kernel shoud fail with an error rather than silently ignore them so that we have more freedom in future flags semantics. To help userspace with handling such errors, inform the client which flags are supported by kernel. For that purpose, we need to allow passing cookies as part of extack also in case of error (they can be only passed on success now). ==================== 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.
