Subject: net: dsa: mv88e6xxx: Request for stable inclusion

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
