 This option is most useful for debugging.  It reduces switching
 performance, so it should not be used in production.

+By default, \fBovs\-controller\fR sets up exact-match flows.  This

+flow-setup latency by causing less traffic to be sent up to the

+This option has no effect when \fB-n\fR (or \fB--noflow\fR) is in use

+By default, \fBovs\-controller\fR directs packets to a particular port

+to the OpenFlow \fBOFPP_NORMAL\fR port.  This allows the switch itself
+to make decisions about packet destinations.  Support for
+\fBOFPP_NORMAL\fR is optional in OpenFlow, so this option may not well
