Bitterblue Smith 8587887c7c wifi: rtw88: 8822c: Fix reported RX band width
commit a71ed5898dfae68262f79277915d1dfe34586bc6 upstream.

"iw dev wlp2s0 station dump" shows incorrect rx bitrate:

tx bitrate:     866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2
rx bitrate:     86.7 MBit/s VHT-MCS 9 VHT-NSS 1

This is because the RX band width is calculated incorrectly. Fix the
calculation according to the phydm_rxsc_2_bw() function from the
official drivers.

After:

tx bitrate:     866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2
rx bitrate:     390.0 MBit/s VHT-MCS 9 80MHz VHT-NSS 1

It also works correctly with the AP configured for 20 MHz and 40 MHz.

Tested with RTL8822CE.

README

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.
