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. If ESP_WIFI_AMPDU_RX_ENABLED

achieve better throughput and compatibility with both stations and APs.

help
Set the number of WiFi dynamic RX buffers, 0 means unlimited RX buffers will be allocated
(provided sufficient free RAM). The size of each dynamic RX buffer depends on the size of
the received data frame.
For each received data frame, the WiFi driver makes a copy to an RX buffer and then delivers
it to the high layer TCP/IP stack. The dynamic RX buffer is freed after the higher layer has
successfully received the data frame.
For some applications, WiFi data frames may be received faster than the application can
process them. In these cases we may run out of memory if RX buffer number is unlimited (0).
If a dynamic RX buffer limit is set, it should be at least the number of static RX buffers.

help
Select type of WiFi TX buffers:
If "Static" is selected, WiFi TX buffers are allocated when WiFi is initialized and released
when WiFi is de-initialized. The size of each static TX buffer is fixed to about 1.6KB.
If "Dynamic" is selected, each WiFi TX buffer is allocated as needed when a data frame is
delivered to the Wifi driver from the TCP/IP stack. The buffer is freed after the data frame
has been sent by the WiFi driver. The size of each dynamic TX buffer depends on the length
of each data frame sent by the TCP/IP layer.
If PSRAM is enabled, "Static" should be selected to guarantee enough WiFi TX buffers.
If PSRAM is disabled, "Dynamic" should be selected to improve the utilization of RAM.

For each transmitted data frame from the higher layer TCP/IP stack, the WiFi driver makes a

int "Max length of WiFi SoftAP Beacon"
range 752 1256

help
ESP-MESH utilizes beacon frames to detect and resolve root node conflicts (see documentation). However the
default length of a beacon frame can simultaneously hold only five root node identifier structures,
meaning that a root node conflict of up to five nodes can be detected at one time. In the occurence of
more root nodes conflict involving more than five root nodes, the conflict resolution process will detect
five of the root nodes, resolve the conflict, and re-detect more root nodes. This process will repeat
until all root node conflicts are resolved. However this process can generally take a very long time.
To counter this situation, the beacon frame length can be increased such that more root nodes can be
detected simultaneously. Each additional root node will require 36 bytes and should be added ontop of the
default beacon frame length of
752 bytes. For example, if you want to detect 10 root nodes simultaneously, you need to set the beacon
frame length as
932 (752+36*5).
Setting a longer beacon length also assists with debugging as the conflicting root nodes can be identified
more quickly.
