Config Background
Available modes of the device are RNDIS and CDC-ECM.
RNDIS is a Microsoft proprietary protocol used mostly on top of USB. It provides a virtual Ethernet link to most versions of the Windows and Linux operating systems. A partial RNDIS specification is available from Microsoft, but Windows implementations have been observed to issue requests not included in that specification, and to have undocumented constraints.
CDC-ECM is Ethernet over USB.[1]
