*WiFi AMPDU RX BA window size*

Type: ``int``

Help
====

.. code-block:: none

    Set the size of WiFi Block Ack RX window. Generally a bigger value means
    higher throughput and better compatibility but more memory. Most of time
    we should NOT change the default value unless special reason,
    e.g. test the maximum UDP RX throughput with iperf etc. For iperf test in
    shieldbox, the recommended value is 9~12. If PSRAM is used and WiFi memory
    is preferred to allocat in PSRAM first, the default and minimum value
    should be 16 to achieve better throughput and compatibility with both
    stations and APs.
