+Test case: Tx offload multi_segs setting
+======================================================
+
+1. Start testpmd with "--tx-offloads=0x00008000" to enable tx_offload multi_segs ::
+
+    ./testpmd -c 0xf -n 4  -- -i --tx-offloads==0x00008000
+    testpmd> show port 0 tx_offload configuration
+    Tx Offloading Configuration of port 0 :
+      Port : MULTI_SEGS
+      Queue[ 0] : MULTI_SEGS
+
+2. Set fwd to txonly, Set the length of each segment of the TX-ONLY packets, Set the split policy for TX packets, then start to send pkgs::
+
+    testpmd> set fwd txonly
+    testpmd> set txpkts 64,64
+    testpmd> set txsplit rand
+    testpmd> start
+
+3. Check TX-packets will not hang and continue to increase::
+    Wait 15s or more, check TX-packets will continue to increase and can be more than 300K
+
+    testpmd> show port stats all
+    testpmd> stop
+    testpmd> quit
+
+4. Start testpmd again without "--tx-offloads", check multi-segs is disabled by default::
+
+    ./testpmd -c 0xf -n 4  -- -i
+    testpmd> show port 0 tx_offload configuration
+    No MULTI_SEGS in Tx Offloading Configuration of ports
+
+5. Enable tx_offload multi_segs ::
+    testpmd> port stop all
+    testpmd> port config 0 tx_offload multi_segs on
+    testpmd> port config 1 tx_offload multi_segs on
+    testpmd> port start all
+    testpmd> show port 0 tx_offload configuration
+    Tx Offloading Configuration of port 0 :
+      Port : MULTI_SEGS
+      Queue[ 0] : MULTI_SEGS
+
+6. Set fwd to txonly, Set the length of each segment of the TX-ONLY packets, Set the split policy for TX packets, then start to send pkgs::
+
+    testpmd> set fwd txonly
+    testpmd> set txpkts 64,64
+    testpmd> set txsplit rand
+    testpmd> start
+    testpmd> show port stats all
+
+7. Check TX-packets will not hang and continue to increase::
+    Wait 15s or more, check TX-packets will continue to increase and can be more than 300K
+
+    testpmd> show port stats all
+    testpmd> stop
+    testpmd> quit
