   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.

 * Because the server always generates 8-byte CIDs, the DCID length cannot be
 * smaller than 8 even if the client received an Initial or Retry packet from
