pure-n ; HT-greenfield mode.

Ie, there's no 11bg interop, everythingo n the channel is 11n, so the
PPDU doesn't include the legacy pieces before the HT pieces. Thus the
packet timing is slightly shorter.

I think though that the savings gained isn't all that much. I'd prefer
that we had a cleaner way to configure disabling say, 11b only clients
from associating, or easier ways of setting the lowest basic rate(s)
to use.
