    ovs-hybrid: should permanently keep MAC entries

    The linux bridge installed for the particular vif type ovs-hybrid
    should be configured to persistently keep the MAC learned from the
    RARP packets sent by QEMU when starting on destination node. That to
    avoid any break of the datapath during a live-migration. That because
    at some point of the live-migration source and destination can be on
    a same L2 and we could have the destination bridge learning from source.
