Linville, Pau Koning, linux-wireless, jouni, vthiagar, senthilb The common->macaddr field is also updated in the ath9k driver (function ath9k_calculate_iter_data in main.c). I just did a quick test. When using macchanger to assign a random MAC address, the original (permanent) MAC address is still retrieved properly. So there is no need to reload the module, macchanger can simply restore the permanent MAC. I assume the permanent MAC address is saved elsewhere?
