Store the started state into a new flag DEVICE_STARTED_SUSPEND and set this when suspending while the device was started. We can't check for is_interface_present() since only mac80211 knows if there are monitor interfaces present. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
