The config protocol is part of the upcoming OF 1.0 spec 
(http://openflowswitch.org/wk/index.php/Config_Protocol).  The idea is 
to have a more robust method of managing less dynamic switch state (in 
particular, configuration).

GRE however is not in OF (yet) so this will be an extension to the 
config protocol schema.
