 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
 option allows it to set up wildcarded flows, which may reduce

+The optional \fIwildcard_mask\fR is an OpenFlow wildcard bitmask in

+\fIwildcard_mask\fR is specified, the default value 0x2820F0 is used

 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).
