The property is used to control duplicate address detection:
* -1 means default value
* 0 means no DAD is performed
* > 0 means timeout (in milliseconds) for arping responses
[bgalvani: moved setting from NMSettingIP4Config]
This is an Ubuntu-specific patch to enable wireless powersave by default.
Should it not work for you for some reason, you can safely add:
powersave=0
to the section:
[802-11-wireless]
In the configuration file for your connection under
/etc/NetworkManager/system-connections/.
The function can now be called on unrealized devices before the
initial unmanaged flags are set and for those devices
nm_device_get_managed() will return TRUE. Since we only accept
states > UNMANAGED, return early when the condition is not met.
Fixes the following failed assertion:
carrier_changed: assertion 'priv->state >= NM_DEVICE_STATE_UNAVAILABLE' failed

Helper macros to define GObject property enum,
the obj_properties array, and a _notify() function.
We should move away from invoking property changed notifications by
string, as we already do for signals. This macro simplifies the
implementation of establishes a pattern for naming and usage.
Commit ac6522bbf1 moved logging of the environment
after the check for @error_message to avoid a crash. However, in case of no
scripts (request->scripts->len == 0) we still want to log the environment,
so move it back to where it was, but avoid the crash.
The availability checks are called from places that don't assume the device
will be removed mid-air. Call the removal routine only when we're the very
last thing that's being done.
During nm_device_unrealize(), the connection might still
have some connections that only get removed later. We must
garbage collect unrealized devices when they loose their
available-connections, not during unrealize.
Fixes: 436ec5b8e3
We possibly need the unrealized device for connections that need
this. nm_device_unrealize() will check if there are still any
available-connections and possibly emit DEVICE_REMOVED signal.

Adding a route via iproute2 with explicit gateway 0.0.0.0
sets the route scope to GLOBAL, contrary to a on-link device-route
which has scope LINK.
Add a test adding two such routes.
Apply MTU and hop limit when managed or other flag is set as well. This wasn't
the case for the first RA and the previous commit made it slightly worse by
always ignoring it.

When a new device gets added or when an existing one changes name,
virtual connections that refer to it as parent device may become
ready, so let's try to activate them.
Previously we tried to activate virtual connections only on startup
and, after commit d8e1590c50 ("manager: retry device creation for
connection that would use a newly created device"), also when a
connection was added/changed, but this doesn't cover the case in which
a parent device appears or changes name at runtime.
https://bugzilla.redhat.com/show_bug.cgi?id=1275875
With DHCPv6 it might be quite some time (we may even time out) until we get all
the information to finish activation, but we already have the addresses and
routes.
With the final removal the reason of NOW_UNMANAGED causes the cleanup on the
device to be run, which downs the device:

The function returns early when autoconnect is off, so there's no reason to
branch for that case below. The signal is only generated for autoconnect=true.
When there's a slave that allows autoconnection and an unrealized master this
would cause the master activation to fail.
For the actual auto-activations the proper check is already done in NMPolicy's
auto_activate_device().
complete_request() possibly frees the request, making the @script and @request
a dangling pointer. We must not use those pointers, except a plain pointer-
comparison.
The request could have been completed by the call to complete_request() just above.
In that case we should just return instead of looking for nowait scripts to run.
