+Flow Filtering Tests
+====================
+
+The Basic RTE flow filtering sample application is a simple example
+of a creating a RTE flow rule. It is intended as a demonstration
+of the basic components RTE flow rules.
+The Flow Filtering results are produced using ''flow'' application::
+
+    ./flow -l 1 -n 1
+
+There is a flow rule defined in the sample code.
+You can check the detailed information of the flow rule from
+http://doc.dpdk.org/guides/sample_app_ug/flow_filtering.html
+
+The matching item is dst IP address: "192.168.1.1".
+The match action is entering the queue 1.
+
+Prerequisites
+=============
+The DUT must have one 10G Ethernet ports connected to one port on
+Tester that are controlled by packet generator::
+
+    dut_port_0 <---> tester_port_0
+
+Assume the DUT 10G Ethernet ports' pci device id is as the following::
+
+    dut_port_0 : "0000:05:00.0"
+    mac_address: "00:00:00:00:01:00"
+
+Bind the port to dpdk igb_uio driver::
+
+    ./usertools/dpdk-devbind.py -b igb_uio 05:00.0
+
+Test Case: match rule
+=====================
+1. Start the application with default settings::
+
+    ./flow -l 1 -n 1
+
+2. Send packets which matches the defined rule from tester::
+
+    Pkt1 = Ether(dst="00:00:00:00:01:00")/IP(src="0.0.0.0", dst="192.168.1.1") \
+    /Raw("x"*20)
+    Pkt2 = Ether(dst="00:00:00:00:01:00")/IP(src="0.0.0.1", dst="192.168.1.1") \
+    /Raw("x"*20)
+
+3. Check the packets are received by queue 1::
+
+    src=A4:BF:01:07:47:C8 - dst=00:00:00:00:01:00 - queue=0x1
+    src=A4:BF:01:07:47:C8 - dst=00:00:00:00:01:00 - queue=0x1
+
+Test Case: dismatch rule
+========================
+1. Start the application with default settings::
+
+    ./flow -l 1 -n 1
+
+2. Send packet which dismatches the defined rule from tester::
+
+    Pkt1 = Ether(dst="00:00:00:00:01:00")/IP(src="0.0.0.0", dst="192.168.1.2") \
+    /Raw("x"*20)
+
+3. Check the packet is not received by queue 1::
+
+    src=A4:BF:01:07:47:C8 - dst=00:00:00:00:01:00 - queue=0x0
