I suggest having a look into the batman layer 3 sources. There you can find a 
kernel module which does exactly what you want:
http://www.open-mesh.org/browser/trunk/batman/linux/modules
Although the setup API is a bit batman specifc (the batman daemon controlled 
the module) you could easily strip the batman API and replace it with 
something more generic.
