+Using the Userspace Datapath with ovs-openflowd
+-----------------------------------------------
+
+To use ovs-openflowd in userspace mode, specify a datapath name that
+begins with "netdev@", and specify --ports with the names of the ports
+that should be included in the datapath as argument. For example:
+
+ ovs-openflowd netdev@br0 --ports=eth0,eth1,eth2
+
+ovs-openflowd will create a TAP device as the bridge's local
+interface, named the same as the bridge minus the "netdev@" prefix.
