Ping-Ke Shih aaefb18333 mac80211: allow non-standard VHT MCS-10/11
[ Upstream commit 04be6d337d37400ad5b3d5f27ca87645ee5a18a3 ]

Some AP can possibly try non-standard VHT rate and mac80211 warns and drops
packets, and leads low TCP throughput.

    Rate marked as a VHT rate but data is invalid: MCS: 10, NSS: 2
    WARNING: CPU: 1 PID: 7817 at net/mac80211/rx.c:4856 ieee80211_rx_list+0x223/0x2f0 [mac8021

Since commit c27aa56a72b8 ("cfg80211: add VHT rate entries for MCS-10 and MCS-11")
has added, mac80211 adds this support as well.

After this patch, throughput is good and iw can get the bitrate:
    rx bitrate:	975.1 MBit/s VHT-MCS 10 80MHz short GI VHT-NSS 2
or
    rx bitrate:	1083.3 MBit/s VHT-MCS 11 80MHz short GI VHT-NSS 2

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.
