Hi,
I am running kernel 6.1 on a system with a mv88e6320 and can easily trigger a flood of "mv88e6085 30be0000.ethernet-1:00: VTU member violation for vid 10, source port 5" messages.
When this happens, the Ethernet audio that passes through the switch causes a loud noise in the speaker.
Backporting the following commits to 6.1 solves the problem:
4bf24ad09bc0 ("net: dsa: mv88e6xxx: read FID when handling ATU violations") 8646384d80f3 ("net: dsa: mv88e6xxx: replace ATU violation prints with trace points") 9e3d9ae52b56 ("net: dsa: mv88e6xxx: replace VTU violation prints with trace points")
Please apply them to 6.1-stable tree.
Thanks,
Fabio Estevam
