+  VF needs the PF interrupt support initialized even if not started.
+
+* **ixgbe: Fixed TX hang when RS distance exceeds HW limit.**
+
+  Fixed an issue when TX queue can hang when a lot of highly fragmented
+  packets have to be sent.
+  As part of that fix, tx_rs_thresh for ixgbe PMD is not allowed to be greater
+  then to 32 to comply with HW restrictions.
+
 * **i40e: Fixed base driver allocation when not using first numa node.**
 
   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,
+  as long as the total number of queues used in PF, VFs, VMDq and FD does not
+  exceeds the hardware maximum.
+
+* **i40e: Fixed statistics of packets.**
+
+  Added discarding packets on VSI to the stats and rectify the old statistics.
