No problem, I'm here for any question :)

It is an EAL parameter. No? just say to EAL which devices to create..

No, what's about vdev? vdevs may manage devices(even whitlist PCI devices) by themselves and want to prevent any app to use these devices(see fail-safe PMD).

Yes, see in main function (the first FOREACH).

Thanks, Matan.
