Description Dan Winship 2020-03-02 23:43:37 UTC 
There are bugs with the IPv6DualStack feature flag in 1.17/4.4 even in single-stack clusters. Bug 1794376 removed it from openshift/api and updated cluster-kube-apiserver-operator but didn't update machine-config-operator so we were still setting that flag for kubelet
