Maybe add a CLI command or similar to re-enable the high
rates for those not interested in using dbus?

Also, it looks like this steps on any previous available-rates
selection logic in supplicant?  It would be nice if this
code took the configured rate settings into account,
having the logic in this patch never enable rates
previously disabled.

Thanks,
Ben
