That would be relevant if this protocol used TCP or UDP.
My understanding is that it doesn't, in which case those port

Looking at the protocol types listed in /usr/include/net/ethernet.h
seems more relevant, unless I have misunderstood something.

Are you sure that IANA would be the right organisation, since AIUI this
isn't a protocol running on top of IP ?
