I hope not. I don't like the idea of forcing the lowest rate in
mac80211; we should allow rate control algorithms to be improved to do
more intelligent selection of rate at least for multicast/broadcast
frames. That might also be of use for some (likely post-association)
unicast management frames since their use is going to increase in the
future.
