837/** 838int freq_reg_info(struct wiphy *wiphy, u32 center_freq, u32 *bandwidth,
838 * freq_reg_info - get regulatory information for the given frequency
839 * @wiphy: the wiphy for which we want to process this rule for
840 * @center_freq: Frequency in KHz for which we want regulatory information for
841 * @bandwidth: the bandwidth requirement you have in KHz, if you do not have one
842 * you can set this to 0. If this frequency is allowed we then set
843 * this value to the maximum allowed bandwidth.
844 * @reg_rule: the regulatory rule which we have for this frequency
845 *
846 * Use this function to get the regulatory rule for a specific frequency on
847 * a given wireless device. If the device has a specific regulatory domain
848 * it wants to follow we respect that unless a country IE has been received
849 * and processed already.
850 *
851 * Returns 0 if it was able to find a valid regulatory rule which does
852 * apply to the given center_freq otherwise it returns non-zero. It will
853 * also return -ERANGE if we determine the given center_freq does not even have
854 * a regulatory rule for a frequency range in the center_freq's band. See
855 * freq_in_rule_band() for our current definition of a band -- this is purely
856 * subjective and right now its 802.11 specific.
