Btw, could you give me a clue about the benefits of pmtud of this esp
packets?

Neither the esp layer seems to honour it and keeps sending with its origin
mtu (interface mtu - esp overhead) nor the original sender ever gets
propagated a lower mtu (I assume because it is tricky to return the original
packet header needed for the dest unreachable msg).
At least at 2.6.15 only a message ("pmtu discovery on SA ESP...") is thrown
by the kernel.
