+the same features (and syntax) as \fBovs\-dpctl\fR(8). Unlike

+These commands are used to expose internal information (mostly statistics)
+about the ``dpif-netdev'' userspace datapath. If there is only one datapath
+(as is often the case, unless \fBdpctl/\fR commands are used), the \fIdp\fR
+argument can be omitted.
+.IP "\fBdpif-netdev/pmd-stats-show\fR [\fIdp\fR]"
+Shows performance statistics for each pmd thread of the datapath \fIdp\fR.
+The special thread ``main'' sums up the statistics of every non pmd thread.
+The sum of ``emc hits'', ``masked hits'' and ``miss'' is the number of
+packets received by the datapath. Cycles are counted using the TSC or similar
+facilities (when available on the platform). To reset these counters use
+\fBdpif-netdev/pmd-stats-clear\fR. The duration of one cycle depends on the
+measuring infrastructure.
+.IP "\fBdpif-netdev/pmd-stats-clear\fR [\fIdp\fR]"
+Resets to zero the per pmd thread performance numbers shown by the
+\fBdpif-netdev/pmd-stats-show\fR command. It will NOT reset datapath or
+bridge statistics, only the values shown by the above command.
+.IP "\fBdpif-netdev/pmd-rxq-show\fR [\fIdp\fR]"
+For each pmd thread of the datapath \fIdp\fR shows list of queue-ids with
+port names, which this thread polls.
