From IPv6 Option Types are 8-bit values, structured as
three subfields, are defined in section 4.2:
Each distinct 8-bit Option Type identifies a different option, i.e., the
high-order 3 bits are considered part of the option identification.
However, it is recommended that Option Types be assigned with distinct
values in the "rest" subfield, until and unless that 5-bit space becomes
full.
