This patch adds support for the new struct ieee80211_rate_status and its
annotation in struct ieee80211_tx_status in minstrel_ht.
In minstrel_ht_tx_status, a check for the presence of instances of the
new struct in ieee80211_tx_status is added. Based on this, minstrel_ht
then gets and updates internal rate stats with either struct
ieee80211_rate_status or ieee80211_tx_info->status.rates.
Adjusted variants of minstrel_ht_txstat_valid, minstrel_ht_get_stats,
minstrel_{ht/vht}_get_group_idx are added which use struct
ieee80211_rate_status and struct rate_info instead of the legacy structs.
struct rate_info from cfg80211.h does not provide whether short preamble
was used for the transmission. So we retrieve this information from VIF
and STA configuration and cache it in a new flag in struct minstrel_ht_sta
per rate control instance.
Compile-Tested: current wireless-next tree with all flags on
Tested-on: Xiaomi 4A Gigabit (MediaTek MT7603E, MT7612E) with OpenWrt

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.
