Why, of all frames, probe response frames should be corrupted I don't know - I could imagine auth/assoc replies being treated differently since they are now with a station entry rather than without. > This only breaks AP mode (station mode works fine). It also has no impact on anything but AP mode, as even indicated by the name of the flag :) Anyway, I was pretty sure this was safe and it does help other drivers to have the full state, but I guess you can make the driver opt out of the flag again (just unset it before register_hw). johannes
