.SH OPTIONS
-.IP "\fB\-n\fR, \fB\-\-noflow\fR"
+.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
packets being seen. If \fBpermanent\fR is specified, which is not
recommended, flows will never expire. The default is 60 seconds.
.IP
-This option affects only flows set up by the OpenFlow controller. In
-some configurations, the switch can set up some flows
-on its own. To set the idle time for those flows, pass
-\fB\-\-max\-idle\fR to \fBovs\-openflowd\fR (on the switch).
-.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\-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[\fIwildcard_mask\fR]"
+.IQ "\fB\-\-wildcards\fR[\fB=\fIwildcard_mask\fR]\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
+flow setup latency by causing less traffic to be sent up to the
controller.
.IP
+The optional \fIwildcard_mask\fR is an OpenFlow wildcard bitmask in
+hexadecimal that specifies the fields to wildcard. If no
+\fIwildcard_mask\fR is specified, the default value 0x2820F0 is used
+which specifies L2-only switching and wildcards L3 and L4 fields.
+Another interesting value is 0x2000EC, which specifies L3-only
+switching and wildcards L2 and L4 fields.
+.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"
+.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.
+.IP
+This option is incompatible with \fB\-N\fR or \fB\-\-normal\fR and
+with \fB\-H\fR or \fB\-\-hub\fR. If more than one is specified then
+this option takes precedence.
+.IP
+This option may be useful for testing or debugging quality of service
+setups.
+.
+.IP "\fB\-Q \fIport-name\fB:\fIqueue-id\fR"
+.IP "\fB\-\-port\-queue \fIport-name\fB:\fIqueue-id\fR"
+Configures packets received on the port named \fIport-name\fR
+(e.g. \fBeth0\fR) to be output on OpenFlow queue ID \fIqueue-id\fR
+(specified as a decimal number). For the specified port, this option
+overrides the default specified on \fB\-q\fR or \fB\-\-queue\fR.
+.IP
+This option may be specified any number of times with different
+\fIport-name\fR arguments.
+.IP
+This option is incompatible with \fB\-N\fR or \fB\-\-normal\fR and
+with \fB\-H\fR or \fB\-\-hub\fR. If more than one is specified then
+this option takes precedence.
+.IP
+This option may be useful for testing or debugging quality of service
+setups.
+.
+.IP "\fB\-\-with\-flows \fIfile\fR"
+When a switch connects, push the flow entries as described in
+\fIfile\fR. Each line in \fIfile\fR is a flow entry in the format
+described for the \fBadd\-flows\fR command in the \fBFlow Syntax\fR
+section of the \fBovs\-ofctl\fR(8) man page.
+.IP
+Use this option more than once to add flows from multiple files.
