openshift-sdn is no longer supported for new installs as of 4.15, and it will be completely removed from OpenShift in 4.17.

Your component currently has one or more CI jobs that use openshift-sdn:

ci-operator/config/openshift/kubernetes/openshift-kubernetes-master.yaml
  e2e-aws-multitenant
  e2e-metal-ipi

These jobs will need to be removed or migrated to ovn-kubernetes by OCP 4.17. In some cases, if you were not intentionally testing openshift-sdn, it may make sense to start migrating these jobs in 4.15. You may want to split this bug into multiple bugs for different OCP versions.

Component-specific notes:

• openshift/kubernetes uses the common pattern of testing baremetal with sdn+ipv4 (e2e-metal-ipi) and ovn+ipv6 (e2e-metal-ipi-ovn-ipv6). Depending on your testing needs, it may make sense to remove the sdn+ipv4 job and keep just the ovn+ipv6 one, or to replace the sdn+ipv4 job with ovn+ipv4, or to replace both jobs with a single ovn+ipv4 job.
• I'm not really sure why o/k is running e2e-aws-multitenant in the first place... It can probably stop immediately.
