The bug happens when virtual network is using VNM_MAD = fw/bridge and keep_empty_bridge isn’t true. When this PR got merged it didn’t add the extracted function to the NoVLANDriver child class and the deactivate action triggered the dummy VLANDriver function which throws an error.

Nice to hear this, I don’t have time to prove it is a bug.
