Bug description:
The kernel built with this packages does have VXLAN compiled.
It would be nice if this could be fixed since VXLAN is used by Flannel and
maybe other CNI plugins for Kubernetes.
$ grep -i vxlan /boot/config-4.4.0-1039-kvm
# CONFIG_VXLAN is not set
When running a kubernetes cluster with Flannel with this image:
$ kubectl logs kube-flannel-ds-amd64-jfkc8 -n kube-system
