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.
