Note that hostapd never directly depended on crda, it just needs/wants it to have the correct regulatory information in the kernel (crda puts it there) after switching the country (hostapd can do that if possible) and then hostapd retrieves the information. But in any case, the whole step with crda is no longer needed if you have the regulatory file (and possibly signature) in place, the firmware will load them as firmware files. johannes
