==============
The interfaces of Connection Manager will always export all services that are

-them. This is of course suboptimal since the user doesn't need to be bothered
-with a device that he/she can actually physically see.
-
-So in this case the user interface can choose to just not show Ethernet
-devices with a favorite=no setting. This is an advanced tweak that is up
-to the user interface. However it is highly recommended to not show Ethernet

database of the WiMAX service.
For Bluetooth the device alias is used. The alias is different since it
is not in use at all at the moment. It also is not attempting to connect
or do anything else.
-With Ethernet services a special "carrier" state is available. It indicates
-that the cable has been plugged in. This state is only used when the device
-is from type Ethernet.
-
The "association" state indicates that this service tries to establish a
low-level connection to the network. For example associating/connecting
with a WiFi access point.
With the "configuration" state the service indicates that it is trying
to retrieve/configure IP settings.
-Some service might require special authentication procedure like a web based
-confirmation. The "login" should be used for this in the future. Currently
-this is not implemented.
-
The "ready" state signals a successful connected device. This doesn't mean
it has the default route, but basic IP operations will succeed.
