Data yang model defines a table features inside of table grouping. OVS 2.4 finally supports table features. Now large table features data are stored inside of each table. It means 254 table features are stored in DS. This ability allow skip pulling and storing of large table features. Table features are still available via rpc but if set to true then maintenance in DS will be omitted and DS latency for inventory will be the same as by OVS >=2.3.

Reason: the inefficient table features fetch were always causing a significant performance drop regardless of whether DIDM or any other features needing table features were enabled or not. If I remember right - the decision was to turn off the table features on stable/beryllium & add the riskier fix on the master first & then maybe port it to the stable/beryllium after some time it has been baked in (may be in the next SR). So it would be better to release note it I think. Yes, so lets do it. Do you have a short 3-4 line description Jozef for release note (explaining why it was changed)?

But if this change is for lithium plugin, i think the impact is minimal, so i think if we can release note it, that would be better.
