Poller in the IXP has too large MTU, it tries to send ping packets with max_size+1, if they work, customer has too large MTU. Also it tries to send max_size, if it does not work, customer has too small MTU. As icing on top, it tries to send max_size+1 but fragments it to max_size and 1, and sees what comes back.
