The QCA4019 firmware 10.4-3.2.1-00050 reports only HT MCS rates between
0-9. But 802.11n MCS rates can be larger than that. For example a 2x2
device can send with up to MCS 15.
The firmware encodes the higher MCS rates using the NSS field. The actual
calculation is not documented by QCA but it seems like the NSS field can be
mapped for HT rates to following MCS offsets:
* NSS 1: 0
* NSS 2: 8
* NSS 3: 16
* NSS 4: 24
This offset therefore has to be added for HT rates before they are stored
in the rate_info struct.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
