Thank you Marek. :)

Yes, I have noticed the potential problem with TTL. At this moment, TTL
setting must be the same throughout the whole network for zebra metrics to be
calculated correctly. I will try to implement a more appropriate metric
calculation based on actual link quality as soon as I feel familiarized
enough with the BATMAN protocol.
