restoring forgotten device

[Gene Czarcinski <gczarcinski gmail com>]

OK, I give up ... what is the "magic dance" I need to do to restore a 
forgotten NIC?

I was "playing" with gnome's network editor and on the reset page for a 
device, I hit the "Forget" button.  Device was "removed" but now I would 
like to "restore it".  How do I do that (other than to do another 
complete install of Fedora 20)?
