Will this always be the same as the OS version?  I think the
controller / user space may be more interested in OVS version,

For example, on my ubuntu system, I got the following output:
versmagic: 3.13.0-19-generic SMP mod_unload modversions

It is hard to decipher which OVS version was selected by the
distribution, or contains modifications or back-ports by distribution
in general.

On the other hand, if this feature is useful for redhat distribution,
and make sense within this scope, I don't see any harm in adding it in
case
OVS version is not directly obtainable.

Make sense? What do you think?
