La implementaci\u00f3n actual del controlador bond netevent solo verifica si el netdev manejado es el representante VF y falta una verificaci\u00f3n si el representante VF est\u00e1 activado. el mismo dispositivo f\u00edsico del v\u00ednculo que maneja el evento neto. Para solucionarlo, agregue la verificaci\u00f3n que falta y optimice la verificaci\u00f3n si netdev es el representante de VF para que no acceda a datos privados no inicializados y se bloquee.
