I would like to be able to tell what type of interface I am dealing with. For example, wifi, ethernet, ...

There are C++ libraries which do it (openscreen linux, mac, and windows.

It would be quite useful when listing interfaces in a mdns implementation.

Is it something already in the pipeline or up to grab?

If nobody is working on it yet, how could we implement it? I assume we could have to create two new const in pnet_sys and make sure these flags are set in windows.rs/unix.rs?
