 Examples
 ~~~~~~~~
 
+* **IP-Pipeline Application.**
+
+  The following features have been added to ip_pipeline
+  application;
+
+  * Added Multiple Producers Multiple Consumers (MPSC)
+    and fragmentation/reassembly support to software rings.
+
+  * Added dynamic pipeline reconfiguration feature that
+    allows binding pipeline to other threads at runtime
+    using CLI commands.
+
+  * Added Enable/disable of promisc mode from ip_pipeline
+    configuration file.
+
+  * Added check on rx queues and tx queues of each link
+    whether they are used correctly in ip_pipeline
+    configuration file.
+
+  * Added flow id parameters to the flow-classification
+    table entries.
+
+  * Added more functions to the routing pipeline, for examples,
+    Fast-path ARP table enable/disable, Double-tagged VLAN
+    (Q-in-Q) packet enacapsulation for the next-hop, MPLS
+    encapsulation for the next-hop, Add colour (Traffic-class
+    for QoS) to the MPLS tag, Classification action to select
+    the input queue of the hierarchical scehdular (QoS).
+    All these functions can be enabled or disabled thorugh
+    congifuration file.
+
+  * Added flow-actions pipeline to ip_pipeline application.
+    Some of the operations of flow classification pipeline
+    such as traffic metering/marking (for e.g. Two Rate Three
+    Color Marker (trTCM)), policer can be performed separately
+    in flow-actions pipeline to avoid excessive computational
+    burden on the CPU core running the flow-classification
+    pipeline.
+
+  * Modified the passthrough pipeline's actions-handler to
+    implement a generic approach to extract fields from the
+    packet's header and copying them to packet metadata. The
+    fields are selected at the desired offset on the basis
+    of the mask specified in application configuration file.
+    The extracted fields, for instance, can be used to compute
+    hash for the lookup table. This feature exposes more
+    flexibility to the users as they will be able to employ
+    new protocol headers and specify the required fields to be
+    extracted.
