Thanks for the clarification. The basic rates vs. supported rates were a bit ambiguous to me. My underlying motivation was to disable lower 2.4GHz bitrates, i.e. 1 through 5.5Mbit/s, to conserve airtime. Is such a hotplug script nevertheless the best to disable such low rates? (Or likewise any patch to allow specification of supported rates via UCI?)
