This option is most useful for debugging. It reduces switching
performance, so it should not be used in production.
+.
+.IP "\fB-w\fR, \fB--wildcard\fR"
+By default, \fBovs\-controller\fR sets up exact-match flows. This
+option allows it to set up wildcarded flows, which may reduce
+flow-setup latency by causing less traffic to be sent up to the
+controller.
+.IP
+This option has no effect when \fB-n\fR (or \fB--noflow\fR) is in use
+(because the controller does not set up flows in that case).
+.
+.IP "\fB-N\fR, \fB--normal\fR"
+By default, \fBovs\-controller\fR directs packets to a particular port
+or floods them. This option causes it to direct non-flooded packets
+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
+with some non-Open vSwitch switches.
+.
+.IP "\fB--mute\fR"
+Prevents ovs\-controller from replying to any OpenFlow messages sent
+to it by switches.
+.IP
+This option is only for debugging the Open vSwitch implementation of
+``fail open'' mode. It must not be used in production.
