bridge doesn't call the filters on outbound.
That only affects locally generated packets. It is debatable whether
that is a bug or a (questionable) design decision. The impact on
existing setups needs to be evaluated; I'm very unsure. But then I'm
not the biggest bridge fan on earth and have never seen anyone using
the bridge filters in a real world scenario until now, afair.
ok?
