These release nodes are somewhat vague. There is nowhere mentioned
that QinQ is not supported, just that layer 2 protocol tunneling
isn't. Or am I overlooking something?

It's nice that you can configure QinQ even if it isn't working... :(

Well I'll have to wait vor 52SG then.. thanks for the explanation.
