We need to find a way to implement this then, in such a way
that we have the route context used to send the ping packet
out.

The problem is RAW sockets right?  If so, then this is where the
fix belongs.

Hm, I've just tried with tracepath (udp) and I also don't see the
pmtu informations cached.

I still had no time to look deeper into the new inetpeer code,
I've just gave it a quick try. I'll try to find out what's going on.
