ports will not work with the userspace datapath, only with the
kernel module.
-Q: Why are there so many different ways to dump flows?

+Implementation Details
+----------------------
+
+Q: I hear OVS has a couple of kinds of flows. Can you tell me about them?
A: Open vSwitch uses different kinds of flows for different purposes:
current version of Open vSwitch, hardware switch
implementations do not necessarily use this architecture.
- Each of the commands for dumping flows has a different purpose:
+ Users and controllers directly control only the OpenFlow flow
+ table. Open vSwitch manages the datapath flow table itself, so
+ users should not normally be concerned with it.
+
+Q: Why are there so many different ways to dump flows?
+
+A: Open vSwitch has two kinds of flows (see the previous question), so
+ it has commands with different purposes for dumping each kind of
+ flow:
- "ovs-ofctl dump-flows <br>" dumps OpenFlow flows, excluding
hidden flows. This is the most commonly useful form of flow
