+Recommended Matching List
+-------------------------
+
+It is highly recommended to upgrade the i40e kernel driver and firmware to
+avoid the compatibility issues with i40e PMD. Here is the suggested matching
+list which has been tested and verified. The detailed information can refer
+to chapter Tested Platforms/Tested NICs in release notes.

   Currently hot-plugging of representor ports is not supported so all required

+- ``Use latest supported vector`` (default ``disable``)
+
+  Latest supported vector path may not always get the best perf so vector path was
+  recommended to use only on later platform. But users may want the latest vector path
+  since it can get better perf in some real work loading cases. So ``devargs`` param
+  ``use-latest-supported-vec`` is introduced, for example::
+
+  -w 84:00.0,use-latest-supported-vec=1
+
+Vector RX Pre-conditions
+~~~~~~~~~~~~~~~~~~~~~~~~
+For Vector RX it is assumed that the number of descriptor rings will be a power
+of 2. With this pre-condition, the ring pointer can easily scroll back to the
+head after hitting the tail without a conditional check. In addition Vector RX
+can use this assumption to do a bit mask using ``ring_size - 1``.
