This series of commits has the end goal of allowing per-port data stored
in the Open vSwitch DB to be transported during live migration. This is
done by first providing a generic infrastructure for transporting network
data, adding some utility functions specific to Open vSwitch, and hooking
the two together.
The framework provided is generic in that other networking data could be
transferred as well by simply adding in additional hooks as needed.

V2 of this patch series fixes some issues found when migrating VMs on
standard Linux bridges.
Kyle Mestery (3):
Add the ability for the Qemu V3 migration protocol to include
transporting network configuration. A generic framework is proposed
with this patch to allow for the transfer of opaque data.
Add utility functions for Open vSwitch to both save per-port data
before a live migration, and restore the per-port data after a
live migration.
Transport Open vSwitch per-port data during live migration by
using the utility functions virNetDevOpenvswitchGetMigrateData()
and virNetDevOpenvswitchSetMigrateData().
