Ativando o Dual NIC do Intel 82575 PCI Controller, Ubuntu

Question

Estou usando o Ubuntu 16.04 e instalei o PCI Dual Nic com o chipset Intel 82575. Esta placa é reconhecida e o driver igb é atribuído a ela, mas apenas uma das interfaces se torna ativa.

Como configuro o driver para reconhecer ambas as interfaces?
