If a 5 GHz radio is calibrated for operation in both the low band (channels 36 to 64) and high band(channels 100 to 169), hardware allows operations in all the listed channels. However, if the chip has been calibrated only for the low/high band and a high/low band channel is configured, due to lack of calibration there will be potentially invalid signal on those non calibrated channels. To avoid this problem this patch sets IEEE80211_CHAN_DISABLED flag for those non calibrated channels by using low_5ghz_chan and high_5ghz_chan values which we get from target through wmi service ready event. Driver initialized flags are getting re initialized in handle_channel in cfg80211. So calling the function to disable the non supported channel from reg_notifier().

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.
