 "

   When an Initial packet is sent by a client that has not previously

   received an Initial or Retry packet from the server, it populates the

   Destination Connection ID field with an unpredictable value.  This

   MUST be at least 8 bytes in length.

 * smaller than 8 even if the client received an Initial or Retry packet from
