will controller program all the tables in a single shot for a single flow entry or will it send different messages for each of the tables for a single flow entry?

How a controller will program a switch when it has to program multiple flow tables for a single flow entry?

For eg, assume there are 3 flow tables supported in the hardware. A flow entry need to be added into all the hardware flow tables. whether controller will send a single message to the switch saying that the flow entry need to be programmed on all the tables or will it send a different message for each of the flow table for the same flow entry?

I believe, the latter one is the mechanism which should be used. But, just want it get clarified. can someone clarify me?

What do you mean by multipe flow tables for single flow entry? By definition a single flow entry can be in a single table. Table ID is part of the Flow Mod message. So, yes, you will will have to send multiple messages for each of the flow tables and each of those will count as a separate flow.
