EthernetInfo: Pull the required information from framework

* Reading from props only goes so far, especially when a static IP is used (never goes to the prop)
* However, Amlogic implemented a class for Ethernet Device information (EthernetDevInfo), but failed to use it.
* Lets use the class they kindly created and neglected to poll the info relevant for the summaries
