+.IP "\fB\-n\fR"
+.IQ "\fB\-\-noflow\fR"
By default, \fBovs\-controller\fR sets up a flow in each OpenFlow switch
whenever it receives a packet whose destination is known due through
MAC learning. This option disables flow setup, so that every packet
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\-H\fR, \fB\-\-hub\fR"
+.IP "\fB\-H\fR"
+.IQ "\fB\-\-hub\fR"
By default, the controller acts as an L2 MAC-learning switch. This
option changes its behavior to that of a hub that floods packets on
all but the incoming port.
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"
+.IP "\fB\-w\fR"
+.IQ "\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
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"
+.IP "\fB\-N\fR"
+.IQ "\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
This option is only for debugging the Open vSwitch implementation of
``fail open'' mode. It must not be used in production.
.
+.IP "\fB\-q \fIid\fR"
+.IQ "\fB\-\-queue=\fIid\fR"
+By default, \fBovs\-controller\fR uses the default OpenFlow queue for
+sending packets and setting up flows. Use one of these options,
+supplying \fIid\fR as an OpenFlow queue ID as a decimal number, to
+instead use that specific queue.

+This option may be useful for debugging quality of service setups.
