+Executing Tunnel encapsulation+decapsulation tests
+--------------------------------------------------
+
+The OVS DPDK encapsulation_decapsulation tests requires IPs, MAC addresses,
+bridge names and WHITELIST_NICS for DPDK.
+
+The test cases can test the tunneling encap and decap without using any ingress
+overlay traffic as compared to above test cases. To achieve this the OVS is
+configured to perform encap and decap in a series on the same traffic stream as
+given below.
+
+TRAFFIC-IN --> [ENCAP] --> [MOD-PKT] --> [DECAP] --> TRAFFIC-OUT
