In Open vSwitch a bond does not have a network device that you can
configure with ifconfig.  If you need a network device to configure, you
can create an "internal" device (like mgmt0 above) and ifconfig that.
Since the internal device is bridged to the bond, the functionality is
equivalent.

Make sure that whatever you want to talk to is connected to the bridge,
for example on eth0 or eth1 in this case.
