If you have to configure the throughput manually why not configure the link with something like 5mbit/s instead of 100kbit/s ? Batman-adv does not care that this throughput is not exact. All that matters is provide input to the algorithm to allow batman-adv to make smart choices.
Yes, today I have changed throughput to 1mbit/s and it works as expected. I just wanted to make sure it was the right way. Thnks to all
