Technical Summary

IETF currently defines format for IPV6[RFC2460] with LOWPAN encapsulation in RFC4944. However the L2
MAC frame is using the same ethertype for both IPv6 datagram[RFC2460] and IPv6 with LOWPAN encapsulation[RFC4944].
This works fine when RFC4944 was written for only IEEE802.15.4 L2 medium. As time progressed, several
other ethertype based L2 technolgies found usefulness in using RFC4944 defined LOWPAN encapsulation methods
for optimized usage of IPv6 in certain use cases.
For example, Wi-SUN Alliance intends to use the 15.9 Multiplexed Data Information Element to dispatch
LoWPAN encapsulation frames to upper stack layers. As specified in IEEE 802.15.9, dispatch of
LoWPAN encapsulation frames will require an Ethertype be assigned for LoWPAN encapsulation.

WiFi Alliance's HALOW standard ( Low power operation in 900 MHZ band) and other L2 technolgies such as
Ethernet and Wireshark will benefit from having a separate ethertype for IPv6 datagrams with LOWPAN
encapsulation.

Additionally, any existing or future Layer 2 technology, incorporating Ethertype based upper layer dispatch,
can use the Ethertype proposed in this document to dispatch LoWPAN encapsulated IPv6 datagrams.
