I rethought about this and to be consistent with the other engine data, I
changed to as per you suggested
and I submitted v5. Kindly take a look -
https://patchwork.ozlabs.org/project/openvswitch/list/?series=176066

I would like to revisit this later and  see if it's really required to
clean up all the runtime data in every recompute or
it can be preserved.
