Ok, good point. Paul's case was regulatory related, where we
(voluntarily) ceased 40 MHz transmissions.

Still though, I think reconfiguring the channel type rather than the
rate control algorithm doesn't make a lot of sense in this case since
it'd make this very special and unlike the other cases (e.g. AP mode).
