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
