igb prend c’est pour la carte réseau double.
e1000e c’est pour la carte réseau sur la carte mère.
e1000 n’est pas utilisé.

Les deux dernières lignes c’est quand j’ai fait un “rmmod igb”.

J’ai l’impression qu’il y a un mélange dans les rename car e1000e et igb sont en concurrence :

le process serait :

rmmod e1000
rmmod e1000e
rmmod igb
insmod e1000e

à confirmer.

la commande “lspci -v” permet de voir le drivers utilisé :
