When the possibility for it to be true will exist, _all_ switchdev
drivers will need to be updated to ignore that (mlxsw, cpss, ocelot,
rocker, prestera, etc etc), not just DSA. And you don't need to
propagate the is_locked flag to all individual DSA sub-drivers when none
care about is_locked in the ADD_TO_DEVICE direction, you can just ignore
within DSA until needed otherwise.

Maybe I have it wrong, but I think that Ido requested me to send it to 
all
the drivers, and have them ignore entries with is_locked=true ...

I don't think Ido requested you to ignore is_locked from all DSA
drivers, but instead from all switchdev drivers maybe. Quite different.

So without changing the signature on port_fdb_add(). If that is to avoid 
changing that signature, which needs to be changed anyhow for any 
switchcore driver to act on it, then my next patch set will change the 
signarure also as it is needed for creating dynamic ATU entries from 
userspace, which is needed to make the whole thing complete.

As it is already done (with the is_locked to the drivers) and needed for 
future application, I would like Ido to comment on it before I take 
action.

In any case I'm going to take a look at this patch set more closely and
run the selftest on my Marvell switch, but I can't do this today
unfortunately. I'll return with more comments.

Yes :-)
