+* **Added support for VxLAN & NVGRE checksum off-load on X550.**
+
+ * Added support for VxLAN & NVGRE RX/TX checksum off-load on
+ X550. RX/TX checksum off-load is provided on both inner and
+ outer IP header and TCP header.
+ * Added functions to support VxLAN port configuration. The
+ default VxLAN port number is 4789 but this can be updated
+ programmatically.
+
+* **Added new X550EM_a devices.**
+
+ Added new X550EM_a devices and their mac types, X550EM_a and X550EM_a_vf.
+ Updated the code to use the new devices and mac types.
+
+* **Added x550em_x V2 device support.**
+
+ Only x550em_x V1 was supported before. Now V2 is supported.
+ A mask for V1 and V2 is defined and used to support both.
+
+* **Supported link speed auto-negotiation on X550EM_X**
+
+ Normally the auto-negotiation is supported by FW. SW need not care about
+ that. But on x550em_x, FW doesn't support auto-neg. As the ports of x550em_x
+ are 10G, if we connect the port with a peer which is 1G, the link will always
+ be down.
+ We added the support of auto-neg by SW to avoid this link down issue.
+
+* **Added sw-firmware sync on X550EM_a.**
+
+ Added support for sw-firmware sync for resource sharing.
+ Use the PHY token, shared between sw-fw for PHY access on X550EM_a.
+
+* **Updated the i40e base driver.**
+
+ The i40e base driver was updated with changes including the
+ following:
+
+ * Use Rx control AQ commands to read/write Rx control registers.
+ * Add new X722 device IDs, and removed X710 one was never used.
+ * Expose registers for HASH/FD input set configuring.
