Desde el commit 4e096a18867a (\"net: introduzca el puntero espec\u00edfico de CAN en la estructura net_device\"), la verificaci\u00f3n de que dev->type sea ARPHRD_CAN ya no es suficiente ya que los dispositivos de red vinculados o sintonizados afirman ser dispositivos CAN pero no inicializan ml_priv en consecuencia."
