 Deletes all flow entries from datapath \fIdp\fR's flow table.
+.SS "CONNECTION TRACKING TABLE DEBUGGING COMMANDS"
+The following commands are primarily useful for debugging the connection
+tracking entries in the datapath.
+.
+.PP
+The \fIdp\fR argument to each of these commands is optional when
+exactly one datapath exists, in which case that datapath is the
+default.  When multiple datapaths exist, then a datapath name is
+required.

+.PP
+\fBN.B.\fR(Linux specific): the \fIsystem\fR datapaths (i.e. the Linux
+kernel module Open vSwitch datapaths) share a single connection tracking
+table (which is also used by other kernel subsystems, such as iptables,
+nftables and the regular host stack).  Therefore, the following commands
+do not apply specifically to one datapath.

+Prints to the console all the connection entries in the tracker used by
+\fIdp\fR.  If \fBzone=\fIzone\fR is specified, only shows the connections
+in \fBzone\fR.  With \fB\-\-more\fR, some implementation specific details
+are included. With \fB\-\-statistics\fR timeouts and timestamps are
+added to the output.

+Flushes all the connection entries in the tracker used by \fIdp\fR.
+If \fBzone=\fIzone\fR is specified, only flushes the connections in
+\fBzone\fR.
