Description Dumitru Ceara 2023-04-21 15:37:09 UTC 
Description of problem:
The OVS kernel datapath hash is not a stable hash (see bug 2175716).  Once bug 2188084 is resolved ovn-controller can determine the type of hash is supported by the underlying datapath and decide whether to use "dp_hash" or "hash".
