How about this library bug???
I haven't seen a true fix for it yet. The Pi force defaults tunl0 to MTU = 0 and you can't adjust ttl. It doesn't matter if you tear it all down the second you load the ipip module and ifconfig tunl0 or ip tunnel add, it force defaults MTU = 0 (auto sense) to which it expects fragmentation.
