History
Salvatore Orlando a9050757d9 Avoid re-wiring ports unnecessarily 
In the majority of cases a port_update notification pertains
a change in the properties affecting port filter, and does
not affect port wiring, ie: the local vlan tag.

This patch simply avoids doing port wiring/unwiring if the
local vlan tag did not change.
The extra overhead for the ovs-db get operation is offset
by the fact that get commands are generally faster than
set commands, and by avoiding executing the ovs-ofctl operation.

Partial-Bug: #1253993
Partially implements blueprint: neutron-tempest-parallel

README 

The Open vSwitch (OVS) Neutron plugin is a simple plugin to manage OVS
features using a local agent running on each hypervisor.
