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