I don't think "just following FreeBSD" is a good reason.
We would like to know the reason why FreeBSD guys put them into libc.

According to description of their eui64(3), theses functions are
"IEEE EUI-64 conversion and lookup routines," so we should think
which other utility could use such functions.
http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/net/eui64.3

I don't know what is EUI64, but netinet6/in6_ifattach.c contains
some EUI64 definitions. So could other network programs use it?
