Currently, when initializing an action, the user-space can specify and use arbitrary values for the tcfa_action field. If the value is unknown by the kernel, is implicitly threaded as TC_ACT_UNSPEC. This change explicitly checks for unknown values at action creation time, and explicitly convert them to TC_ACT_UNSPEC. No functional changes are introduced, but this will allow introducing tcfa_action values not exposed to user-space in a later patch. Note: we can't use the above to hide TC_ACT_REDIRECT from user-space, as the latter is already part of uAPI. v3 -> v4: - use an helper to check for action validity (JiriP) - emit an extack for invalid actions (JiriP) v4 -> v5: - keep messages on a single line, drop net_warn (Marcelo) Signed-off-by: Paolo Abeni <pabeni@redhat.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

README
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
