Interesting. So are you saying that you're trying to disable the
low(er) rates by not having the client systems advertise them, possibly
because you can't manipulate the transmitter to not use them?
But that seems a bit strange, since basic/mandatory rates always need
to be supported?

It seems that your implementation is closer to what I was suggesting
though :)
