As the title suggests, I'm using a mac book pro with os x 10.9.2 and I connect to the network through the ethernet adapter thunderbolt.
Is there a way to get a reference icon in the menu bar, as is the case for the wifi?
I'd prefer not to use applications such as iStatsMenu or similar ..

I think I will be forced to lean against third-party apps, even if they are all a bit 'suck!
