Hello.

Recently I was reviewing some code that adds support for two RFC 5447 RADIUS AVPs below:

   The MIP6-Home-Link-Prefix AVP (AVP Code 125) is of type OctetString
   The MIP6-Feature-Vector AVP (AVP Code 124) is of type Unsigned64 and

It turned out, the current RADIUS Types registry at https://www.iana.org/assignments/radius-types/radius-types.xhtml lists both attributes with wrong types:

125 	MIP6-Home-Link-Prefix 	ipv6prefix 	[RFC5447]
124 	MIP6-Feature-Vector 	string 	[RFC5447]

Those incorrect types had propagated from the IANA registry into FreeRADIUS and Wireshark (both have been fixed now for MIP6-Home-Link-Prefix, see the discussion and the follow-ups at https://github.com/the-tcpdump-group/tcpdump/pull/636 if interested).

Having studied this discrepancy thoroughly, I had concluded the AVP definitions are correct in RFC 5447, so I did not file an erratum. The problem seems to be with those IANA allocations only. Could somebody review this issue and put the IANA allocations right?

Thank you.
