Awesome :) I will add a patch to ovs-dpctl that will turn the
sys.exit(0) into sys.exit(1) - that way it should do the skip.
When I previously tested, I put an error in the `try` without reading
the except being specifically for a ModuleNotFound error.
I'll make sure pyroute2 isn't installed when I run it again.
Thanks for your help Jakub and Paolo!
