I do not understand this patch. It seems to me that it basically blocks
any future use of dynamic fdb entries from userspace towards drivers.

I would have expected that something would be done in the DSA layer,
where (switchcore) drivers would be able to set some flags to indicate
which features are supported by the driver, including non-static
fdb entries. But as the placement here is earlier in the datapath from
userspace towards drivers it's not possible to do any such thing in the
DSA layer wrt non-static fdb entries.

As explained too many times already in the thread here:

Ahh yes thanks, I see the comment you wrote on march the 27th.
