The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still present in\nthe current wireless tree.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have\ncompatible Libertas USB hardware for exercising this firmware-download\npath, no runtime testing was able to be performed."
