+Packet Ordering Application
+============================
+
+The Packet Ordering sample app simply shows the impact of reordering a stream.
+It's meant to stress the library with different configurations for performance.
+
+Overview
+--------
+
+The application uses at least three CPU cores:
+
+* RX core (maser core) receives traffic from the NIC ports and feeds Worker
+  cores with traffic through SW queues.
+
+* Worker core (slave core) basically do some light work on the packet.
+  Currently it modifies the output port of the packet for configurations with
+  more than one port enabled.
+
+* TX Core (slave core) receives traffic from Worker cores through software queues,
+  inserts out-of-order packets into reorder buffer, extracts ordered packets
+  from the reorder buffer and sends them to the NIC ports for transmission.
+case test_packet_ordering
+---------------------------
+Compiling the Application
+
+The application execution command line is:
+
+.. code-block:: console
+
+    ./packet_ordering [EAL options] -- -p PORTMASK [--disable-reorder]
+
+The -c EAL CPU_COREMASK option has to contain at least 3 CPU cores.
+The first CPU core in the core mask is the master core and would be assigned to
+RX core, the last to TX core and the rest to Worker cores.
+
+The PORTMASK parameter must contain either 1 or even enabled port numbers.
+When setting more than 1 port, traffic would be forwarded in pairs.
+For example, if we enable 4 ports, traffic from port 0 to 1 and from 1 to 0,
+then the other pair from 2 to 3 and from 3 to 2, having [0,1] and [2,3] pairs.
+
+The disable-reorder long option does, as its name implies, disable the reordering
+of traffic, which should help evaluate reordering performance impact.
