Originally, nm-remote-settings was used by the daemon to monitor the
user settings service, and its subclass nm-remote-settings-system was
used by NM clients to monitor the system settings service. With user
settings services gone, this distinction is no longer needed. Simplify
things a bit and merge the classes.
Now that we have only one settings service, there is no more need to
have common settings service code in libnm-glib. So we can simplify
things somewhat my moving everything from nm-settings-service into
nm-sysconfig-settings.
Remove code related to "connection scope" and such. Later, we will also
do lots of code flattening and simplification that's possible now that
user settings are gone.
This commit implements MAC cloning feature in NetworkManager. To support that,
'PermHwAddress' property is added into *.Device.Wired and *.Device.Wireless
interfaces. The permanent MAC address is obtained when creating the device, and
is used for 'locking' connections to the device. If a cloned MAC is specified
in connection to be activated, the MAC is set to the interface in stage1. While
disconecting, the permanent MAC is set back to the interface.
Track missing firmware and ensure the device can't be used when firmware
is missing. Add a property for missing firmware so that clients can do
something intelligent with this information.
Since forever we've used sleep/wake as the way to implement
Networking Enabled. When the state file was introduced to make the
networking and wifi states persistent, we ran into a bug where
a failed suspend (like if the machine ran out of power while
suspended) would result in networking being disabled on reboot
since suspend/resume used the same knob as enable/disable.
This patch adds a distinct call for enable/disable networking
which changes the state file, while sleep/wake no longer change
the state file.
