And if a router receives a to large IP packet is should send an ICMP "fragmentation needed and DF set" when it cannot be fragmented by the router.

The problem is we keep the payload on layer 2, so that it never will bubble up to layer 3, hence never emit fragmentation needed (we even might not have an IP address). All you see is a hanging connection.

Is there any tunneling protocol which support ethernet frame fragmentation?

Good question.
