(with the -dd option). I don't have physical access to any hardware given the current crisis, but if you could tell which kernel and wpa_supplicant version you applied the patch on, and whether you took the patches from the mailing list or from git including the cleanup patches. Also, which driver/card did you use ? I mainly tested this with ath9k with ar93xx.
