Kuan-Chung Chen d360551f26 wifi: rtw89: introduce beacon tracking to improve connection stability
In ideal scenario, AP's beacon should transmit at the Target Beacon
Transmission Time (TBTT). However, in practice, beacon may be slightly
off-schedule. This beacon "drift" prevents the firmware from receiving
beacon at the expected TBTT, leading to connection disruptions.

To address this, we introduce beacon tracking mechanism to enhance overall
connection stability. This mechanism executes the following steps in each
cycle (2 seconds): 1) Based on the last 32 received beacons, compute the
minimum TBTT offset to use for the next cycle 2) Using the same 32 beacons,
calculate the drift of each. A histogram is plotted, and outliers are
identified using a boxplot. 3) According to the statistical results from
the second step, a maximum receive window size (beacon timeout) is selected
to cover approximately 80% of the beacons and applied to the next cycle.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
