Before NM 1.2, the way to change IP settings on a device is to first
update the stored configuration with your new details, and then ask NM
to reconfigure the interface with your updated stored connection. In
more detail:
1) read the connection object
2) read the connection's secrets and merge them into the connection
object (or if you have them already, just merge them)
3) change the IP settings to whatever you want
4) send the full package back to NetworkManager with
Settings.Connection.Update()
5) request re-activation of the connection with
Manager.ActivateConnection()
this is what you see in the Python examples gi/update-ip4-method.py and
dbus/update-ip4-method.py.
With NM 1.2 and later, you can change some details (like IP settings)
on-the-fly without a full reactivation using the Device.Reapply()
method, and this does not require updating the stored configuration.
However, since it doesn't require updating the stored connection,
these changes will be lost when the device is deactivated, so to
preserve these changes you must update the stored connection too.
