The blamed commit and others in that patch set started the trend of reusing existing DSA driver API for a new purpose: calling ds->ops->port_fdb_add() on the CPU port. The lantiq_gswip driver was not prepared to handle that, as can be seen from the many errors that Daniel presents in the logs: [ 174.050000] gswip 1e108000.switch: port 2 failed to add fa:aa:72:f4:8b:1e vid 1 to fdb: -22 [ 174.060000] gswip 1e108000.switch lan2: entered promiscuous mode [ 174.070000] gswip 1e108000.switch: port 2 failed to add 00:01:02:03:04:02 vid 0 to fdb: -22 [ 174.090000] gswip 1e108000.switch: port 2 failed to add 00:01:02:03:04:02 vid 1 to fdb: -22 [ 174.090000] gswip 1e108000.switch: port 2 failed to delete fa:aa:72:f4:8b:1e vid 1 from fdb: -2 The errors are because gswip_port_fdb() wants to get a handle to the bridge that originated these FDB events, to associate it with a FID. Absolutely honourable purpose, however this only works for user ports. To get the bridge that generated an FDB entry for the CPU port, one would need to look at the db.bridge.dev argument. But this was introduced in commit |

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 reStructuredText 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.
