Introduce a debugfs option to manually override the noise floor, ignoring the automatically tuned noise floor of the driver/hw.
In my tests with a AR9580 based module and a tx99 5 MHz interferer, I could tune the noisefloor to -95 dBm or above to allow communication again. The automatic noise floor calibration sometimes could adapt to the situation as well, but not reliably and permanently.
I would consider this "feature" experimental and interesting for people debugging the noise floor calibration or other effects of the hardware.
