+Pipeline Tests
+=============================
+
+Description
+===========
+The "examples/pipeline" application is the main DPDK Packet Framework
+application.
+
+Prerequisites
+==============
+The DUT must have four 10G Ethernet ports connected to four ports on
+Tester that are controlled by the Scapy packet generator::
+
+    dut_port_0 <---> tester_port_0
+    dut_port_1 <---> tester_port_1
+    dut_port_2 <---> tester_port_2
+    dut_port_3 <---> tester_port_3
+
+Assume four DUT 10G Ethernet ports' pci device id is as the following::
+
+    dut_port_0 : "0000:00:04.0"
+    dut_port_1 : "0000:00:05.0"
+    dut_port_2 : "0000:00:06.0"
+    dut_port_3 : "0000:00:07.0"
+
+Bind them to dpdk igb_uio driver::
+
+    ./usertools/dpdk-devbind.py -b igb_uio 0000:00:04.0 0000:00:05.0 0000:00:06.0 0000:00:07.0
+
+Supporting Files
+================
+All the supporting files for this test suite are maintained in a tar file named "pipeline.tar.gz"
+present in the {DTS_SRC_DIR}/dep directory.
+
+Directory Structure of Each Test Case
+=====================================
+Within {DTS_SRC_DIR}/dep/pipeline.tar.gz, all files related to a particular test case are maintained
+in a separate directory of which the directory structure is shown below:
+
+    test_case_name [directory]
+        test_case_name.spec
+        test_case_name.cli
+        table.txt [applicable for test cases requiring it]
+        readme.txt
+        pcap_files [subdirectory]
+            in_x.txt [x: 1-4; depending on test case]
+            out_x.txt [x: 1-4; depending on test case]
+
+For an example, files related to mov_001 test case are maintained as shown below:
+
+    mov_001 [directory]
+        mov_001.spec
+        mov_001.cli
+        readme.txt
+        pcap_files [subdirectory]
+            in_1.txt
+            out_1.txt
+
+Template of each Test Case
+===========================
+1. Edit test_case_name/test_case_name.cli:
+   change pci device id of LINK0, LINK1, LINK2, LINK3 to pci device id of
+   dut_port_0, dut_port_1, dut_port_2, dut_port_3
+
+2. Run pipeline app as the following::
+
+    x86_64-native-linuxapp-gcc/examples/dpdk-pipeline  -c 0x3 -n 4 -- -s /tmp/pipeline/test_case_name/test_case_name.cli
+
+3. Send packets at tester side using scapy. The packets to be sent are maintained in pipeline/test_case_name/pcap_files/in_x.txt
+
+4. Verify the packets received using tcpdump. The expected packets are maintained in pipeline/test_case_name/pcap_files/out_x.txt
+
+5. Test case is considered as successful if the received packets and the expected packets match for all the port combinations used.
+
+Example Test Case: test_mov_001
+=========================================
+1. Edit mov_001/mov_001.cli:
+   change pci device id of LINK0, LINK1, LINK2, LINK3 to pci device id of
+   dut_port_0, dut_port_1, dut_port_2, dut_port_3
+
+2. Run pipeline app as the following::
+
+    x86_64-native-linuxapp-gcc/examples/dpdk-pipeline  -c 0x3 -n 4 -- -s /tmp/pipeline/mov_001/mov_001.cli
+
+3. Send packets at tester side using scapy. The packets to be sent are maintained in pipeline/mov_001/pcap_files/in_1.txt
+
+4. Verify the packets received using tcpdump. The expected packets are maintained in pipeline/mov_001/pcap_files/out_1.txt
+
+5. test_mov_001 is considered as successful if the received packets and the expected packets match for all 4 port combinations used.
