+
+- ``rx_func_hint`` (default ``none``)
+
+  Used to select Rx burst function, supported value are ``vec``, ``sve``,
+  ``simple``, ``common``.
+  ``vec``, if supported use the ``vec`` Rx function which indicates the
+  default vector algorithm, neon for Kunpeng Arm platform.
+  ``sve``, if supported use the ``sve`` Rx function which indicates the
+  sve algorithm.
+  ``simple``, if supported use the ``simple`` Rx function which indicates
+  the scalar algorithm.
+  ``common``, if supported use the ``common`` Rx function which indicates
+  the scalar scattered algorithm.
+
+  When provided parameter is not supported, ``vec`` usage condition will
+  be first checked, if meets, use the ``vec``. Then, ``simple``, at last
+  ``common``.

+- ``tx_func_hint`` (default ``none``)
 
-The following options can be modified in the ``config`` file.
-Please note that enabling debugging options may affect system performance.
