Set the number of WiFi static RX buffers. Each buffer takes approximately 1.6KB of RAM.
The static rx buffers are allocated when esp_wifi_init is called, they are not freed
until esp_wifi_deinit is called.
WiFi hardware use these buffers to receive all 802.11 frames.
A higher number may allow higher throughput but increases memory use.
A higher number may allow higher throughput but increases memory use. If ESP32_WIFI_AMPDU_RX_ENABLED
is enabled, this value is recommended to set equal or bigger than ESP32_WIFI_RX_BA_WIN in order to
achieve better throughput and compatibility with both stations and APs.

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