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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
