Well it is impossible to draw a simple tree showing the configuration
exactly with all details. May be it is too ambitious to draw a tree
at all.

I tried that and failed. I didn't want to have something that would
work only "somehow" as that would create confusion instead of helping.

OK, I give up. My patch was naive and I deleted it.
Nevertheless I still think it would be useful to show network
interfaces dependencies in a pure text format.

Consider the very simple case of an interface with two vlan interfaces
and both of them in a bridge.

         vlan0
      /        \
eth0             br0
      \        /
         vlan1

You can't represent this in a tree view. And this is just a very simple
example, in reality it tends to be much more complex.

Perhaps something like that:
eth0
    vlan0
        br0
    vlan1
        br0
