    some people are interested by a network full isolation/virtualization
    like you did with the layer 2 isolation and some other people are
    interested by a light network isolation done at the layer 3. This one is
    intended to implement "application container" aka "lightweight container".

    In the case of a layer 3 isolation, the network interface is not totally
    isolated and the debate here is to find a way to have something
    intuitive to manage the network devices.

    IHMO, all the discussion we had convinced me of the needs to have the
    possibility to choose between a layer 2 or a layer 3 isolation.

    If it is ok for you, we can collaborate to merge the two solutions in
    one. I will focus on layer 3 isolation and you on the layer 2.
