I just want to be sure. But this implicates that the incomming packet is
already decapusulated by the kernel and it has attached metadata like the
tunnel_id etc.
a nicer solution would be that you can already match on tunnel_id before it
is getting encapsulated. Then you can chose later if it needa decapsulation
or just forward the packet.
I'm not sure if it is a possibility?

Kind regards, Wieger IJntema
