Note that some pdf viewers can't read stdin or require dash as the
parameter to use stdin.

I don't think it's possible to enhance iproute2 to display the network
interface dependencies in an useful way. It's just too complex. It's
not even a (undirected) tree.

I know there is an option to execute something remotely but I think 
a pure text output may be useful to get a quick overview.

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. But neither directory structure is a tree (when consider links)
and there are a plenty of tools showing directory tree.
