IANA Registry for 6lowpan ESC Dispatch Code points

RFC4944 defines ESC dispatch type for additional dispatch bytes in the 6lowpan header. The value of ESC byte has been updated by RFC6282. However, the usage of ESC extension byte has not been defined in RFC6282 and RFC4944. The purpose of this document is to define the ESC extension byte code points and to request corresponding IANA actions.
