Please ignore my comment completely. I was thinking of the u/g bits,
which are NOT relevant to the FF-FF and FF-FE thing, unless I also fail
to count bits correctly. Nevertheless, the significance of bits #57 and
#58 are not widely known to IPv6 operators out there.

No, in my head.

Looks like a mistake indeed, given that FF-FF is according to IEEE
MAC-48, and FF-FE is EUI-48.

Sorry for any confusion.

Daniel
