Terry Wilson ca57c9fe8f Update ovsdb release notes re: new OVS ports
Defaulting ovsdb/of_interface to native causes services to
listen on new ports. On systems using selinux, it is important
to make sure that permission is given to listen on these ports.

prelude: >
Prior to Newton, the default option for 'ovsdb_interface'
was 'vsctl'. In Newton 'ovsdb_interface' defaults to
'native'. This change switches the way of communication
with OVSDB from the ovs-vsctl tool to Open vSwitch python
api to improve out-of-the-box performance for typical
deployments.
upgrade:
- To keep the old default value use 'ovsdb_interface = vsctl'
in '[ovs]' section of openvswitch_agent.ini
(common path '/etc/neutron/plugins/ml2/openvswitch_agent.ini')
if there is a separate openvswitch agent configuration file;
otherwise apply changes mentioned above to ml2_conf.ini
(common path '/etc/neutron/plugins/ml2/ml2_conf.ini').
- The native interface configures ovsdb-server to listen for
connections on 127.0.0.1:6640 by default. The address can be
configured with the ovsdb_connection config option. Ensure that
ovsdb-server has permissions to listen on the configured address.
