According to the Realtek propritary driver and the rtw88 driver, the
tx rates of the ack (includes block ack) are initialized with lower
tx rates (no HT rates) which is set by the RRSR register value. In
real cases, ack rate higher than current tx rate could lead to
difficulty for the receiving end to receive management/control frames.
The retransmission rate would be higher then expected when the driver
is acting as receiver and the RSSI is not good.
Cross out higer rates for ack packet before implementing dynamic rrsr
configuration like the commit 4830872685 ("rtw88: add dynamic rrsr
configuration").

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 Restructured Text 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.
