Hello Sven
Thanks for your answer, I collaborate with Andrei, who asked the question, let me try to help to explain, though I suspect that your message did contain the answer somehow.
We know that batman-adv does multi-hop at L2. That is in fact the problem. We are trying to test how a network utility called simplemux may improve the performance in a mesh network using batman-adv. The idea behind simplemux is that aggregating all packets that node X wants to sent to node Y at any time, making them share the IP header and accessing the channel only once for the bundle, can dramatically improve the performance. Node X should take any packets in the TX queue coming from different sources and probably going to different destinations but having the same next hop, and put them together in a bundle. That is what simplemux does. But actually simplemux operates on a tunnel that takes the packets sent through a physical interface in X and drives them to a physical interface of Y.
We don't know well how the tunnel manages the traffic, but possibly the problem is that it requires the packages coming up from the physical interface to the IP layer (what does not happen in batman-adv), which is actually what you say. In this case, may be we cannot do what we wanted to do :-(
Thanks a lot
Javier

If anyone has any idea why it does not work I would be very grateful.
Sorry, but I still don't get what are you doing with layer 3 tunnel stuff and what batman-adv has to do with it (it is a layer 2 based protocol which requires layer 2 interfaces).
Kind regards, Sven
