Add 'fallback' support. NetworkManager will attempt to brute-force
connect to networks marked as fallback if there are no better wireless
connections available. This is useful as a method of last resort, to
work around driver problems, and for use with hidden networks.
* gnome/applet/applet-dbus-devices.c,
gnome/applet/applet-dbus-devices.h: Add fallback parameter.
* gnome/applet/applet-dbus-info.c: Retrieve fallback bit from Gconf and
pass it on via DBUS.
* gnome/applet/applet.c: No fallback by default.
* gnome/applet/applet.glade, gnome/applet/other-network-dialog.c:
Update other-network-dialog to add UI checkbox toggling fallback.
* src/NetworkManagerAP.c, src/NetworkManagerAP.h: Remove "trusted"
propery from AP object. Add "fallback" property to AP object.
* src/nm-dbus-nm.c: Grab the fallback parameter via DBUS.
* src/nm-dbus-nmi.c: Grab the fallback parameter via DBUS.
* src/nm-device-802-11-wireless.c: Break out blacklist logic into
separate function. Add get_best_fallback_ap() for returning an AP
on which to attempt fallback.
* src/backends/NetworkManagerSuSE.c: Set stored network as fallback.
* test/nm-set-fallback: New file. Sets a given network as fallback.
