The Type/Length field is assigned and controlled by the IEEE which we are delighted to say is now publicly available. IANA maintains a public list of values that have been culled from various sources BUT IS NOT DEFINITIVE and in fact shows a number of conflicts.
The list below was derived from personal inspection and research and is INCOMPLETE and in the interests of consistency will not be maintained. Use the DEFINITIVE IEEE source referenced above.
