"""Convert topo to mininet.topo.Topo instance.
This helper function allows the user to use topologys which are not
direct instances of mininet.topo.Topo in MaxiNet. If the topology was
not converted to a Topo instance the transfer via pyro most likely
fails as the original class might not be available at the pyro remote.
Args:
topo: Instance which fullfills the interface of mininet.topo.Topo.
Returns:
Instance of mininet.topo.Topo,
