+====================================
+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.
+This is the test plan for unit test to verify if XL710 can enable single port
+mac loopback.
+
+Prerequisites
+=============
+
+Two 40Gb Ethernet ports of the DUT are directly connected and link is up.
+bind the port to dpdk driver::
+
+ ./usertools/dpdk-devbind.py -b igb_uio 05:00.0
+
+Test case 1: enable loopback mode
+=================================
+
+1. enable loopback mode:
+In dpdk/test/test/test_pmd_perf.c
+set::
+
+ .lpbk_mode=1
+ #define MAX_TRAFFIC_BURST 32
+
+then make test
+
+2. 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 2: disable loopback mode
+=================================
+
+1. disable lookback mode:
+In dpdk/test/test/test_pmd_perf.c
+set::
+
+ .lpbk_mode=0
+ #define MAX_TRAFFIC_BURST 32
+
+then make test
+
+2. 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.
