This\ncauses a sub-interface to be created with no IEEE80211_SDATA_IN_DRIVER bit\nset because the monitor interface is in the cooked state and it takes\nprecedence over all other states.

Es posible configurar simultáneamente las banderas MONITOR_FLAG_COOK_FRAMES y MONITOR_FLAG_ACTIVE en la misma interfaz de monitor desde el espacio de usuario. Esto provoca que se cree una subinterfaz sin el bit IEEE80211_SDATA_IN_DRIVER configurado, ya que la interfaz de monitor está en estado cocinado y tiene prioridad sobre todos los demás estados. Al eliminar la interfaz, el kernel llama a WARN_ONCE() desde check_sdata_in_driver() debido a la falta de ese bit. Solucione esto rechazando MONITOR_FLAG_COOK_FRAMES si se configura junto con otras banderas.
