Created attachment 1012081 [details] Update to 1.1.0 development snapshot Also solves the bridge bug, as described here: https://mail.gnome.org/archives/networkmanager-list/2015-April/msg00013.html
Fedora 21 is based on nm-0-9-10 release, and likewise Fedora 22 is based on nm-1-0. Updating to a newer major release (or development snapshot) has a huge risk to break other stuff. We can only backport safe fixes to nm-0-9-10/F21. Lets re-target this bug to a specific issue (bridge behavior with networking disabled?). See also: https://bugzilla.gnome.org/show_bug.cgi?id=747477
Why the two of you discuss something that is already done and working, as far as the bridge at least?
