Hello,

thank you for getting back to me so quick. I did some debugging and it
turned out that i40e drivers were not linked when building the dpdk. I
fixed this, but I have encountered another problem...

Although the cards are discovered, I get this error:

> EAL: pci_map_resource(): cannot mmap(102, 0x7fffc0000000, 0x1000000, 0x0): Operation not permitted (0xffffffffffffffff)

I've seen some information about his mmap-related behavior and some
hints about setting iomem=relaxed in grub. As making changes to grub
means completely reinstalling my machine, I would like to ask, if you
think that this could be the way to go.

Thanks,
Martin
