This part: 'authentication': The module adheres to the recommendations in Section 13.2 of [RFC4364] as it allows enabling TCP-AO [RFC5925] and accommodates the installed base that makes use of MD5.

I will probably suggest adding some additional discussion of the weakness of MD5 to the security considerations in my ballot comments, if no such text appears before then.
