In the example you've given, the kernel datapath would execute the actions.
However, ovs-vswitchd would figure out which OpenFlow rule would be best for
the kernel datapath to execute for a particular packet. None of this is
specific to a controller, though; it doesn't matter whether the controller
added that flow or a userspace utility like ovs-ofctl.
You may want to look at this presentation from the openvswitch.org website,
which describes the high-level components and their responsibilities:
