Open vSwitch has two kinds of actions. First, there are OpenFlow
actions, which include both standard actions and extension actions.
"clone" is an OpenFlow extension action implemented by Open vSwitch.
Second, there are datapath actions, which are an implementation detail
of Open vSwitch. Open vSwitch has a datapath action also called
"clone", which does something similar to the OpenFlow extension "clone"
action but at the datapath level.
