which each flow entry is associated with an action telling the switch
how to process the flow, (2) a "secure channel" connecting the switch
to a remote process (a controller), allowing commands and packets to

controller to talk to the switch.

+An OpenFlow switch can thus serve as a simple datapath element that
forwards packets between ports according to flow actions defined by
the controller using OpenFlow commands. Example actions are:
- Drop this flow's packets
- Encapsulate and forward this flow's packets to the controller.

Bugs/Shortcomings
-----------------
-- The current flowtable does not support all statistics messages
- mentioned in the Type 0 OpenFlow spec.
-
- The flowtable does not support the "normal processing" action.
-- Configure/build system does not support separate build directory for
- the datapath. ./configure must be run from the source root.
-
-- dpctl dump-flows may freeze when large numbers of flows are in the
- flow table. This has no effect on the datapath.
