network-manager-applet has a piece of code to create a new default
connection when connecting to a device which doesn't have connection yet.
See function applet_menu_item_activate_helper() in applet.c line 313.
I'm wondering if it's ok to export this piece of code through
org.freedesktop.NetworkManagerUserSettings interface.
Maybe a new method: GetConnectionsForDevice(o: device), which returns
existing connections for a specific device, or creates and returns a new
default connection, if there is no connection for the device yet.
Regards
James Su
