The goal of writing 0x6954341e / 0x6955341e to REG_OFDM0_XA_AGC_CORE1 appears to be setting the initial gain, which is stored in bits 0..6. Bits 7..31 are the same as what the phy init tables write. Modify only bits 0..6 so that we don't have to care about the values of the others. This way we don't have to add another "else if" for the RTL8192FU. Why we need to change the initial gain from the default 0x20 to 0x1e? Not sure. Some of the vendor drivers change it to 0x1e before scanning and then restore it to the original value after.

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.
