+=============================================
+MTU Check
+=============================================
+
+This check will use testpmmd to check if MTU is set to 1500/2400/4800/9000
+as required and appear in the set status.
+
+Prerequisites
+=============
+
+Compile DPDK and testpmd. Be able to have the testpmd run.
+
+Test Case: set MTU size
+==========================================
+
+Run testpmd in interactive mode ::
+
+  $ ./dpdk-testpmd -- -i
+
+This can be run with other arguments as well, depending on your setup.
+
+(port_id) - the id for the port you are working on.
+The port has to be stopped before setting MTU size.
+Run this command in testpmd ::
+
+  testpmd> port stop (port_id)
+
+(mtu_size) - the size for MTU you want to set.
+Run this command in testpmd ::
+  testpmd> port config mtu (mtu_size)
+
+(port_id) - the id for the port you are working on.
+Verify the output from matches with the correct size::
+  testpmd> show port info (port_id)
