API changes

  • Python API: To avoid conflicts between VPP API messages names and the Python API binding function names, VPP API methods are put in 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/
