+====================================
+Unit Tests: single port MAC loopback
+====================================
+
+According to loopback mode, setup loopback link or not.
+If loopback mode is setted, packets will be sent to rx_q from tx_q directly.
+Else if loopback mode is disabled, packets will sent to peer port from tx_q. 
+Loopback mode can be used to support testing task.
+
+
+Prerequisites
+=============
+
+Two 10Gb/25Gb/40Gb Ethernet ports of the DUT are directly connected and link is up.
+
+
+single port MAC loopback
+========================
+
+This is the test plan for unit test to verify if X710/XL710/XXV710 can enable single port
+mac loopback.
+
+Test Case: enable loopback mode
+===============================
+
+In dpdk/test/test/test_pmd_perf.c
+Set::
+
+    .lpbk_mode=1
+    #define MAX_TRAFFIC_BURST              32
+
+Then make test
+Start test::
+
+    ./test/test/test -c f -n 4 -- -i
+    RTE>>pmd_perf_autotest
+
+The final output of the test will be matrix of average cycles of IO used per
+packet, and "Test OK" is printed out.
+The peer port can't receive any packet.
+
+Test Case: disable lookback mode
+================================
+
+In dpdk/test/test/test_pmd_perf.c
+Set::
+
+    .lpbk_mode=0
+    #define MAX_TRAFFIC_BURST              32
+
+Then make test
+Start test::
+
+    ./test/test/test -c f -n 4 -- -i
+    RTE>>pmd_perf_autotest
+
+There is not "Test OK" presented.
+The peer port can receive all the 32 packets.
