Marko,

I had looked at that patch briefly, and it looked like VERY interesting 
work. If it fixes the bridging code, too, it's even better - I'll 
definitly look forward to using it, once it has become a bit more mature.

Yeah, I noticed that three seconds after I hit "send" :-) I moved the 
stuff up into the "if (bif != BDG_LOCAL)" branch. Still, there might be 
duplicate packets delivered to the bpf, I'll look into that today.

Thanks for the feedback!
