+
+- ``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``)
