Podr\u00eda ser que el lag dev sea nulo, as\u00ed que deje de procesar el evento. En bond_enslave(), el esclavo activo/de respaldo se configura antes de configurar el desarrollo superior, por lo que el primer evento es sin un desarrollo superior. Despu\u00e9s de configurar el desarrollo superior con bond_master_upper_dev_link() hay un segundo evento y en ese evento tenemos un desarrollo superior."
