commit a58a527494aa40b11b23eca47a8afb60fb24583a

    Scan for MAC through all devices in macvtap agent
    
    The first device the agent happens to pick could be something
    without a MAC address like a 6in6 interface. This was causing
    the agent to fail to start if it was unlucky enough to pick
    that address.
    
    This patch just adjusts the logic to keep iterating through
    the list until we find a MAC.
