openvswitch2.17-2.17.0-77.el8fdp.x86_64 and openvswitch2.15-2.15.0-133.el8fdp.x86_64 are both provided by the rhel-8-fast-datapath-rpms repo, in 4.12 ansible playbook, we're specifying "openvswitch2.15"[1] to be installed on the RHEL node, while in 4.13, it's already updated to "openvswitch2.17"[2]. 

[1]https://github.com/openshift/openshift-ansible/blob/release-4.12/roles/openshift_node/defaults/main.yml#L85
[2]https://github.com/openshift/openshift-ansible/blob/release-4.13/roles/openshift_node/defaults/main.yml#L85


And looks openvswitch2.15-2.15.0-133.el8fdp.x86_64 couldn't be updated to openvswitch2.17-2.17.0-77.el8fdp.x86_64 directly, it has to be removed before installing the openvswitch2.17 package.
