Re: [PATCH V3 net-next 3/4] net: dsa: mv88e6xxx: mac-auth/MAB implementation

[Hans S]

Hi Vladimir,
maybe you have missed my upstreaming of this patch set...

According to our earlier discussions I have now implemented the
feature, so that the ATU locked entries are owned by the driver, so to
make the entries dynamic I add the entries to a list and use kernel
timers to age out the entries as they should be 'dynamic'. See
mv88e6xxx_switchdev.c.
