+Ordinarily, \fBovs\-openflowd\fR expects the administrator to create
+the specified \fIdatapath\fR and add ports to it externally with a
+utility such as \fBovs\-dpctl\fR.  However, the userspace switch
+datapath is implemented inside \fBovs\-openflowd\fR itself and does
+not (currently) have any external interface for \fBovs\-dpctl\fR to
+access.  As a stopgap measure, this option specifies one or more ports
+to add to the datapath at \fBovs\-openflowd\fR startup time.  Multiple
+ports may be specified as a comma-separated list or by specifying
+\fB\-\-ports\fR multiple times.
