the latest changes in iwn messed up how the rates are calculated.
the PLCP lookup code is doing the wrong thing - it assumes that an 11n channel will always have 11n traffic. However, some management traffic may be non-11n. So, support that.
Some 11n APs get very unhappy if you send them 11n management frames, so don't do that.
