Jiri Pirko says:

====================
switchdev: bring back switchdev_obj

Second version of the patch extends to a patchset. Basically this patchset
brings object structure back which disappeared with recent Vivien's patchset.
Also it does a bit of naming changes in order to get the things in line.
Also, object id is put back into object structure.
Thanks to Scott and Vivien for review and suggestions.
====================
