It allows to identify the wlan kind of device for the user application,
e.g.:

       wlan

have we considered also exposing the mode of this netdev. So for example sta,ap,p2p-go,p2p-client etc. If we can send dynamic updates via RTNL, we could easily tell the networking management system what type of wireless device we have here. I am thinking about it like "wlan/p2p-go" etc. Or should this be better kept strictly to "wlan".

And I am not sure RTNL would be capable of changing this kind strings at runtime anyway.

May be better do not mix 2 things in one attribute?
