+This program works only with datapaths that are implemented outside of
+\fBovs\-vswitchd\fR itself, such as the Linux and Windows kernel-based
+datapaths. To manage datapaths that are integrated into
+\fBovs\-vswitchd\fR, such as the userspace (\fBnetdev\fR) datapath,
+use \fBovs\-appctl\fR(8) to invoke the \fBdpctl/*\fR commands, which
+are documented in \fBovs\-vswitchd\fR(8).
