Reason: This patch has been sitting unchanged for more than 12 weeks. I am therefore going to abandon it to keep the nova review queue sane. Please feel free to restore the change if you're still working on it.

    Assign mac address to vf netdevice when using macvtap port

    This is a workaround to libvirt issue described here:
    https://bugzilla.redhat.com/show_bug.cgi?id=1372944. The problem is that
    libvirt dosn't update the mac address of the netdevice, instead it uses
    netlink to configure the mac address of the VF. For macvtap to work
    libvirt should set the mac address on the VF net device and using
    netlink. Until this is fixed we should set both of them in nova.
