Does Xamarin Have An Ethernet Manager Class?

Hello to everyone:

I need to be able to enable and disable an ethernet connection on android, but i can't find a way to do it, i found this on Java:

http://developer.oesf.biz/em/developer/reference/durian/android/net/ethernet/EthernetManager.html

Here they use the EthernetManager class, wich it's in the Java.Lang.Object - Android.Net.Ethernet.EthernetManager.

But i cant find either Java.Lang.Object nor Android.Net.Ethernet on Xamarin.

I also find this, which im checking now but cant figure out yet.

Does anyone know how to use it?

Thanks for all.
