+Q: Can I use Linux bond devices on Open vSwitch bridges?
+
+A: Yes.  If you are already accustomed to configuring and using Linux
+   bond devices, then you can continue to use them with Open vSwitch.
+   You can add a Linux bond device to an Open vSwitch bridge with
+   "ovs-vsctl add-port", the same way as with other network devices.
+
+   You should not configure an IP address on a Linux bond device that
+   you add to an Open vSwitch bridge.  See the "Configuration
+   Problems" section for more information.
+
+   Linux bonds may have reduced performance compared to Open vSwitch
+   bonds, because Open vSwitch lacks the direct visibility into the
+   attached interfaces that would allow it take advantage of NIC
+   offload features.
+
+   Linux bonds and Open vSwitch bonds have different features.  Linux
+   bonds don't, for example, offer the SLB balancing mode, and cannot
+   because the bond device does not have access to the Open vSwitch
+   MAC table.
+
+Q: It looks like each of the interfaces in my bonded port shows up
+   as an individual OpenFlow port.  Is that right?
+
+A: See the "Controllers" section below.
