J'ai essayé sur une autre machine, avec une carte Intel X520-DA2 plus ancienne, reconnue différemment par LSPCI => même chose : failed to load because an unsupported SFP+ or QSFP module type was detected.
La seconde cage (0000:1a:00.1) s'initialise correctement, car je n'ai pas mis de SFP+ :
dmesg | grep ixgbe :

LSPCI reconnaît directement que c'est une Intel X520-DA2 (elle a 4 ans d'age cette carte)
