OK. Would it be fine fine if I retain the references to MD5 as is 
and add the following text at the end of section 3.2

"The random interface identifier generation algorithm, as described in
this document, uses MD5 as the hash algorithm. The node MAY use another
algorithm instead of MD5 to produce the random interface identifier."

Agreed. Since we are no longer mandating what algorithm to use, I will
remove this reference.

Will do.
