Comment 15 for bug 1827102

FYI: It is prio low, but to not forget about this "other" build issue with 5.1 I filed bug 1838984

Just to be totally sure I did a rebuild with the DPDK in proposed and the current kernel version and things are fine indeed.

ubuntu@bionic:~$ sudo dkms build -m dpdk-rte-kni -v 17.11.6 -k 4.15.0-55-generic

Creating symlink /var/lib/dkms/dpdk-rte-kni/17.11.6/source ->
                 /usr/src/dpdk-rte-kni-17.11.6

DKMS: add completed.
