I believe this is the same bug I reported upstream in October '20 (but
nobody was able to reproduce):

Quoting myself (Comment 11):
----

The issue seems to be finally solved by acceptance of the "RX filtering in
DSA" patch series (thanks to Tobias Waldekranz & Vladimir Oltean).

I tested this with 5.14-rc3 on a Turris Omnia. Traffic from a DSA switch
port, addressed to the bridge, is not flooded anymore to other DSA switch
ports - even if unicast flooding is turned on.
----


So, I guess this would be the series to backport.
