It should go fast as the majority of patches > here are non-x86. crda is a userspace helper, invoked by udev events, which sets -and intersects as needed- the regulatory domain settings for (modern, cfg80211 based) wlan hardware based on the device's EEPROM regdom hint, local configuration (country code) and eventual IEEE 802.11d hints (country IEs) beaconed by access points nearby. It hooks into udev with these udev rules (Debian/ 1.1.2-1): $ grep -v -e ^$ -e ^\# /lib/udev/rules.d/60-crda.rules SUBSYSTEM=="ieee80211", ACTION=="add", RUN+="/lib/crda/setregdomain" $ grep -v -e ^$ -e ^\# /lib/udev/rules.d/85-regulatory.rules KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/crda" Full source is at [2], it should be installed on pretty much every distro/ system released with wlan support for the last >>3 years. There are two iwl4965 patches in this series, which might be among the first ones to check - /if/ you actually have that hardware, the second one (iwl4965: reset firmware after rfkill off) might also indirectly have an effect on blutetooth (via rfkill).
