You will be scared now, but nla_for_each_nested is a for-loop. Please
indent the printf right.
Sure. I will do it.

Such file makes only sense when it's used in more than one file. I don't
see this at the moment.
Btw: wireless "iw" used it in two files "info.c" and "event.c".
Ok. In this case where should i put this code (interface.c)?
My assumption is that in the future we may add same
features that wireless utils is having now.
That is the reason why i created this file :-).
