That's just the IETF draft, it's not in 802.11s.

Linux and FreeBSD include 802.11s, but you have to run a separate tool
It doesn't do any of the "40 loops" stuff, it just stops once it finds
a curve point.
(Though ~line 1034, is it failing after the 16th trial? Is that right?)

Are you sure? I think some people like it. I'll bring it up on
"messaging" list when I have time (or feel free to beat me to it!).
