Code Issues Proposed changes

Drop of_interface option

Browse Source 
Default value for "of_interface" config option was switched
to "native" in Pike release.
In the same release this option was deprecated to removal.
Now it's time to remove it and force use of "native" driver to
manage openflows.

upgrade:
- |
The deprecated ``of_interface`` option is removed. Neutron will
always use the ``native`` driver, which has been the default
since Pike (11.0).
If old driver ``ovs-ofctl`` was used before upgrade, automatically
done change to ``native`` driver will cause short break of data plane
connectivity during neutron-ovs-agent upgrade.
