to request the driver to release mbufs from their Tx ring that are no longer
in use, independent of whether or not the ``tx_rs_thresh`` has been crossed.
+* **Added descriptor status ethdev API.**
+
+ Added a new API to get the status of a descriptor.
+
+ For Rx, it is almost similar to the ``rx_descriptor_done`` API, except
+ it differentiates descriptors which are hold by the driver and not
+ returned to the hardware. For Tx, it is a new API.
+
* **Increased number of next hops for LPM IPv6 to 2^21.**
The next_hop field is extended from 8 bits to 21 bits for IPv6.
+* **Added VFIO hotplug support.**
+
+ How hotplug supported with UIO and VFIO drivers.
+
* **Added powerpc support in pci probing for vfio-pci devices.**
sPAPR IOMMU based pci probing enabled for vfio-pci devices.
+* **Updated the ixgbe base driver.**
+
+ Updated the ixgbe base driver, including the following changes:
+
+ * Add link block check for KR.
+ * Complete HW initialization even if SFP is not present.
+ * Add VF xcast promiscuous mode.
+
+* **Added powerpc support for i40e and its vector PMD .**
+
+ i40e PMD and its vector PMD enabled by default in powerpc.
+
+* **Added VF max bandwidth setting on i40e.**
+
+ i40e HW supports to set the max bandwidth for a VF. Enable this capability.
+
+* **Added VF TC min bandwidth setting on i40e.**
+
+ i40e HW supports to set the allocated bandwidth for a TC on a VF. Enable this
+ capability.
+
+* **Added VF TC max bandwidth setting on i40e.**
+
+ i40e HW supports to set the max bandwidth for a TC on a VF. Enable this
+ capability.
+
+* **Added TC strict priority mode setting on i40e.**
+
+ There're 2 TX scheduling modes supported for TCs by i40e HW, round ribon mode
+ and strict priority mode. By default it's round robin mode. Enable the
+ capability to change the TX scheduling mode for a TC. It's a global setting
+ on a physical port.
+
+* **Added TSO support for tunneled and non-tunneled packets on mlx5 driver.**
+
+ Added support for Hardware TSO for tunneled and non-tunneled packets.
+ Tunneling protocols supported are GRE and VXLAN.
+
+* **Added support for Rx interrupts on mlx5 driver.**
+
+ Rx queues can be armed with an interrupt which will trigger on the
+ next packet arrival.
+
+* **Updated the sfc_efx driver.**
+
+ * Generic flow API support for Ethernet, VLAN, IPv4, IPv6, UDP and TCP
+ pattern items with QUEUE action for ingress traffic.
+
+ * Support virtual functions (VFs)
+
+* **Added LiquidIO network PMD.**
+
+ Added poll mode driver support for Cavium LiquidIO II server adapter VFs.
+
+* **Added support for the Wind River Systems AVP PMD.**
+
+ Added a new networking driver for the AVP device type. Theses devices are
+ specific to the Wind River Systems virtualization platforms.
+
+* **Added vmxnet3 version 3 support.**
+
+ Added support for vmxnet3 version 3 which includes several
+ performance enhancements viz. configurable TX data ring, Receive
+ Data Ring, ability to register memory regions.
+
Resolved Issues
---------------
* removed the build-time setting ``CONFIG_RTE_RING_PAUSE_REP_COUNT``
* removed the function ``rte_ring_set_water_mark`` as part of a general
removal of watermarks support in the library.
+ * added an extra parameter to the burst/bulk enqueue functions to
+ return the number of free spaces in the ring after enqueue. This can
+ be used by an application to implement its own watermark functionality.
+ * added an extra parameter to the burst/bulk dequeue functions to return
+ the number elements remaining in the ring after dequeue.
+ * changed the return value of the enqueue and dequeue bulk functions to
+ match that of the burst equivalents. In all cases, ring functions which
+ operate on multiple packets now return the number of elements enqueued
+ or dequeued, as appropriate. The updated functions are:
+
+ - ``rte_ring_mp_enqueue_bulk``
+ - ``rte_ring_sp_enqueue_bulk``
+ - ``rte_ring_enqueue_bulk``
+ - ``rte_ring_mc_dequeue_bulk``
+ - ``rte_ring_sc_dequeue_bulk``
+ - ``rte_ring_dequeue_bulk``
+
+ NOTE: the above functions all have different parameters as well as
+ different return values, due to the other listed changes above. This
+ means that all instances of the functions in existing code will be
+ flagged by the compiler. The return value usage should be checked
+ while fixing the compiler error due to the extra parameter.
