The more extensive alternative would be adding a way to replay all
static fdb (and mdb) entries to re-add them after flushing the ATU,
then you can allow that any time. This would be also something
interesting for e.g. b53, where disabling (the global) vlan filtering
in hardware means you cannot add or remove (static) entries with VID
!= 0.

But either option is fine for me; my main concern is avoiding a desync
of hardware and software configuration.
