Vladimir Oltean says: ==================== Pass the BR_FDB_LOCAL information to switchdev drivers Bridge FDB entries with the is_local flag are entries which are terminated locally and not forwarded. Switchdev drivers might want to be notified of these addresses so they can trap them. If they don't program these entries to hardware, there is no guarantee that they will do the right thing with these entries, and they won't be, let's say, flooded. Ideally none of the switchdev drivers should ignore these entries, but having access to the is_local bit is the bare minimum change that should be done in the bridge layer, before this is even possible. These 2 changes are extracted from the larger "RX filtering in DSA" series: https://patchwork.kernel.org/project/netdevbpf/patch/20210224114350.2791260-8-olteanv@gmail.com/ https://patchwork.kernel.org/project/netdevbpf/patch/20210224114350.2791260-9-olteanv@gmail.com/ and submitted separately, because they touch all switchdev drivers, while the rest is mostly specific to DSA. This change is not a functional one, in the sense that everybody still ignores the local FDB entries, but this will be changed by further patches at least for DSA. ==================== 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.
