Description Tim Rozet 2022-04-25 14:12:23 UTC

Description of problem:
Multicast ACLs have the wrong name in the external id which causes sync to think the ACL is legacy and needs to be changed to from-lport. This causes multicast to stop working after a restart of the ovnkube-master node.

Verified with 4.11.0-0.nightly-2022-05-18-171831

$ oc get clusterversion

Ran automated multicast test case before and after master nodes being rebooted, test case passed before and after.
