Bon, je viens de tester avec deux SFP+ de Fiberstore, un BiDi non codé et un LR codé intel, aucun des deux ne charge, que ce soit avec le driver do'rigine de la ubuntu 16.10 ou avec la dernière version compilée à la main.
La carte que j'ai installée cette fois est la 82598EB, je vais reessayer avec une 82599 si j'en retrouve dans mon stock.
Est ce qu'on a une idée de la version à laquelle Intel a ajouté ce coup de pute ? Genre pour downgrader et pouvoir enfin utiliser ce matos ?
EDIT : test avec la vraie X520-DA2 qu'il me restait, driver ixgbe 5.0.4

donc le problème vient du 82598EB avec les nouveaux drivers, pas du 82599ES ?
