+
+  *  Add the ability for the upper layer to query RX/TX queue information.
+  *  Add into rte_eth_dev_info new fields to represent information about
+     RX/TX descriptors min/max/align numbers per queue for the device.
+
+* **Added RSS dynamic configuration to bonding.**

   Fixed i40e issue that occurred when a DPDK application didn't initialize
   ports if memory wasn't available on socket 0.
 
+* **i40e: Fixed maximum of 64 queues per port.**
+
+  Fixed the issue in i40e of cannot supporting more than 64 queues per port,
+  though hardware actually supports that. The real number of queues may vary,
