Open vSwitch controllers may store per-port data in the OVS DB on a host. This is
an opaque data blob utilized by a controller to store information relevant to the
port itself. This patch provides a mechanism for this to migrate with the virtual
machine during live migration by adding code to the V3 migration protocol.

Tested migration with "virtualport type='openvswitch'", both with and without this
per-port data. Also tested migration with non-OVS bridges.

Kyle Mestery (1):
  Add the ability to migrate per-port data on Open vSwitch ports    
    during qemu live migration. A controller can use this to store    
    data relating to each port, and have it migrated with the virtual  
      machine and populated on the destination host.
