Tobias Waldekranz 10fae4ac89 net: dsa: include bridge addresses which are local in the host fdb list 
The bridge automatically creates local (not forwarded) fdb entries
pointing towards physical ports with their interface MAC addresses.
For switchdev, the significance of these fdb entries is the exact
opposite of that of non-local entries: instead of sending these frame
outwards, we must send them inwards (towards the host).

NOTE: The bridge's own MAC address is also "local". If that address is
not shared with any port, the bridge's MAC is not be added by this
functionality - but the following commit takes care of that case.

NOTE 2: We mark these addresses as host-filtered regardless of the value
of ds->assisted_learning_on_cpu_port. This is because, as opposed to the
speculative logic done for dynamic address learning on foreign
interfaces, the local FDB entries are rather fixed, so there isn't any
risk of them migrating from one bridge port to another.

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.

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.
