Could the MTU discovery phase take place prior to establishing the
TUN? I.e., send the special DPD and expect a reply within a second or
two. If the reply is received create the device, if not resend a
smaller packet. That would add few seconds of latency in the creation
of the tun device and the channel, but the user wouldn't need to
search for the mtu manually.
