1.  Introduction

   The ITU-T G.9959 recommendation [G.9959] targets low-power Personal
   Area Networks (PANs).  This document defines the frame format for
   transmission of IPv6 [RFC2460] packets as well as the formation of
   IPv6 link-local addresses and statelessly autoconfigured IPv6
   addresses on G.9959 networks.

   The general approach is to adapt elements of [RFC4944] to G.9959
   networks.  G.9959 provides a Segmentation and Reassembly (SAR) layer
   for transmission of datagrams larger than the G.9959 Media Access
   Control Protocol Data Unit (MAC PDU).

   [RFC6775] updates [RFC4944] by specifying IPv6 over Low-Power
   Wireless Personal Area Network (6LoWPAN) optimizations for IPv6
   Neighbor Discovery (ND) (originally defined by [RFC4861]).  This
