As just discussed on IRC, yes and the log for that is at
https://build.opensuse.org/package/live_build_log/home:cpaelzer:branches:home:bluca:dpdk/dpdk-19.11/openSUSE_Tumbleweed/x86_64

It also is affected by an issue around  -Werror=implicit-fallthrough,
so even with KNI fixed it likely is going to fail.

I don't need it, as I have already grabbed and preliminary added it:
https://github.com/cpaelzer/dpdk-stable-queue/commit/d43fa3e198c08a3a76d70f4565b31ad3ab5f29c4

But surely, once/If you come up with a full patch that also includes
tumbleweed I can replace it with yours.
