Current solution: The solution was UNEXPECTEDLY SIMPLE.
We force DF flag on tunnels with preconfigured hop limit,
that is ALL. :-) Well, it does not remove the problem completely,

(branches, that exceed pmtu are pruned) and tunnel mtu

Yes, it is not good if there exists a router in the loop,

But it is not our problem! Nobody could accuse us, we made
GRE tunnels with enabled checksum. Tell them "thank you".
