OVS doesn't support directly outputting to a bond.  The FAQ says:

### Q: It looks like each of the interfaces in my bonded port shows up
   as an individual OpenFlow port.  Is that right?

A: Yes, Open vSwitch makes individual bond interfaces visible as
   OpenFlow ports, rather than the bond as a whole.  The interfaces
   are treated together as a bond for only a few purposes:

   - Sending a packet to the OFPP_NORMAL port.  (When an OpenFlow
     controller is not configured, this happens implicitly to
     every packet.)

   - Mirrors configured for output to a bonded port.

   It would make a lot of sense for Open vSwitch to present a bond as
   a single OpenFlow port.  If you want to contribute an
   implementation of such a feature, please bring it up on the Open
   vSwitch development mailing list at dev at openvswitch.org.
