[Etherlab-users] Dual Ethernet Box and kernel driver configuration

Hello Mike,

If the master starts the interfaces, he removes the igb driver and
loads the ec_igb driver by default.
So both interfaces are managed by the ec_igb driver.
But only one is used for ethercat. The other interface is registered as
normal NIC to the kernel.

Best regards
