API changes
++++++++++++++
* Python API: To avoid conflicts between VPP API messages names and the Python API binding function names, the VPP API methods are put into a separate proxy object https://gerrit.fd.io/r/#/c/5570/
The api methods are now referenced as: vpp_handle = VPP(jsonfiles) vpp_handle.connect(...) vpp = vpp_handle.api vpp.show_version() vpp_handle.disconnect()
For backwards compatibility VPP API methods are left in the main name space (VPP), but will be removed from 17.07.
- Python API: Change from cPython to CFFI.
* create_loopback message to be replaced with create_loopback_instance create_loopback will be removed from 17.07. `<https://gerrit.fd.io/r/#/c/5572/>`_
