[ Upstream commit 20429444e653ee8242dfbf815c0c37866beb371b ] When using rtl8192cu with rtl8xxxu driver to connect wifi, there is a probability of failure, which shows "authentication with ... timed out". Through debugging, it was found that the RCR register has been inexplicably modified to an incorrect value, resulting in the nic not being able to receive authenticated frames. To fix this problem, add regrcr in rtl8xxxu_priv struct, and store the RCR value every time the register is written, and use it the next time the register need to be modified.

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.
