Hey Linus,

we actually want those frames to pass through the mesh - otherwise we can't 
find out if "regular" packets would loop through the mesh, so we have handle 
those special packets like regular ones.

If we don't want to see them, we have to hide them, but we can't remove the 
packet without hurting the functionality. :)

Cheers,
