+Tx Packet Pacing
+~~~~~~~~~~~~~~~~
+
+In order to deliver the timestamp with every packet, a special type of Tx Host
Queue is
+used, the TS Queue. This feature is currently supported only in E830 adapters.
+
+The tx_offload ``RTE_ETH_TX_OFFLOAD_SEND_ON_TIMESTAMP`` is used to enable the
feature.
+For example:
+
+.. code-block:: console
+
+ dpdk-testpmd -a 0000:31:00.0 -c f -n 4 -- -i --tx-offloads=0x200000
+ set fwd txonly
+ set txtimes 30000000,1000000
+ start
