Add the argument '-tree' to ip-link to show network devices
dependency tree.

Example:

$ ip -tree link
eth0
   bond0
eth1
   bond0
eth2
   bond1
eth3
   bond1

Hmm, what is this good for? I'm probably missing something...

I consider this kind of output useful when troubleshooting a complex
configuration with many interfaces. It may show relations among
interfaces.

Did you see https://github.com/jbenc/plotnetcfg ?

Thanks for the link. I haven't seen plotnetcfg and I like it.
It is handy when the analyzed system has GUI.

You can also run it remotelly. Also I believe that you can catch the
state into some dump file and process it later on. Not 100% sure though.
