Jan, To compile DPDK on kernels 4.2 and later, you need two patches submitted to the list last week. The ID's are 7518 - kni-rename-HAVE_NDO_BRIDGE_GETLINK_FILTER_MASK-macro 7519 - kni-fix-igb-build-with-kernel-4.2 And if you're on a 4.3 kernel: 8131 - fix igb_uio's access to pci_dev->msi_list for kernels >= 4.3 Regards, Dave.
