Use interface name in TDENetworkConnectionManager_BackendNM instead of MAC address
This relates to bug 2748
The name of the network interface seems to be a more stable identifier than the MAC
address because the MAC address can be changed easily or even automatically - see
randomization of MAC addresses on wireless interfaces. Therefore, the use of the
MAC address as a network interface identifier was abandoned.
Beware, this change is an API / ABI change! However, most changes are internal
and the only one affected is application TDENetworkManager.
