Reduced frequency of Tx tail pointer updates to the NIC.
+* **Added support for link status interrupts in mlx4.**
+
+* **Added partial support (TX only) for secondary processes in mlx4.**
+
* **Added support for Mellanox ConnectX-4 adapters (mlx5).**
The mlx5 poll-mode driver implements support for Mellanox ConnectX-4 EN
Due to its experimental state this application may change without notice.
The application is supported only for Linux x86_64.
+* **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:
+ ARP table enable/disable, Q-in-Q and MPLS encapsulation,
+ add colour (Traffic-class for QoS) to the MPLS tag.
+
+ * Added flow-actions pipeline for traffic metering/marking
+ (for e.g. Two Rate Three Color Marker (trTCM)), policer etc.
+
+ * Modified the pass-through pipeline's actions-handler to
+ implement a generic approach to extract fields from the
+ packet's header and copying them to packet metadata.
+
Resolved Issues
---------------
The mlx drivers were unable to load when built as a shared library,
due to a missing symbol in mempool library.
+* **mlx4: Performance improvements.**
+
+ Fixed bugs in TX and RX flows that improves mlx4 performance.
+
+* **mlx4: Fixed Tx loss after initialization.**
+
+* **mlx4: Fixed scattered Tx with too many segments.**
+
+* **mlx4: Fixed memory registration for indirect mbuf data.**
+
* **vhost: Fixed Qemu shutdown.**
Fixed issue with libvirt ``virsh destroy`` not killing the VM.
As the l3fwd example application requires this info, the i40e vector
driver must be disabled to benefit of the packet type with i40e.
+* **Mellanox PMDs (mlx4 & mlx5):**
+
+ * PMDs do not support DPDK integrated shared library.
+
+ * There is performance degradation for small packets when PMD
+ is compiled with SGE_WR_N = 4 compared to the performance when SGE_WR_N = 1.
+ If scattered packets are not used it is recomended
+ to compile PMD with SGE_WR_N = 1.
+
+ * When a Multicast or Broadcast packet is sent to the SR-IOV mlx4 VF,
+ it is returned back to the port.
+
API Changes
-----------
* librte_cfgfile: Allow longer names and values by increasing the constants
CFG_NAME_LEN and CFG_VALUE_LEN to 64 and 256 respectively.
+* vhost: a new field enabled is added to the vhost_virtqueue structure.
+
+* vhost: a new field virt_qp_nb is added to virtio_net structure, and the
+ virtqueue field is moved to the end of virtio_net structure.
+
+* vhost: a new operation vring_state_changed is added to virtio_net_device_ops
+ structure.
+
+* vhost: a few spaces are reserved both at vhost_virtqueue and virtio_net
+ structure for future extension.
