6.1.4 Care-of Test Init Message

   Mobility Options

      Variable-length field of such length that the complete Mobility
      Header is an integer multiple of 8 octets long.  This field
      contains zero or more TLV-encoded mobility options.  The receiver
      MUST ignore and skip any options which it does not understand.
      This specification does not define any options valid for the
      Care-of Test Init message.
