   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.

   * 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.
