rtl8192cu handles 1T1R devices (RTL8188CUS), 1T2R devices (RTL8191CU), and 2T2R devices (RTL8192CU). The 2T2R devices were incorrectly detected as 1T2R because of a mistake in the IS_92C_1T2R macro. The visible effect of this is that the firmware was allowed to use TX rates only up to MCS7. Fix the IS_92C_1T2R macro. Now my 2T2R device has much better upload speed. Before: 46 Mbps. After: 82 Mbps. Also fix a debug message which was printing "RF_1T1R" even for 1T2R chips.

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.
