I think ODC Driver does not have to set any values into "hardTimeout" and "idleTimeout".
I think ODC driver should omit to set any values into these attributes, and should let VTN Manager use its default value.

The above explanation is not about the "hardTimeout", but about the "idleTimeout".

The flow entries configured in switch by the VTN are removed after the specified time in "hardTimeout" attribute elapses, regardless of whether or not packets are hitting the entries.

For more detailed information, please see the following page.

Also, I think OpenFlow specification helps you understand about "hardTimeout" and "idleTimeout".
