The ath patch number is already large and adding other patch for ath11k
will add more confusion with the patch numbering.
Since the support of ath11k based device is imminent, prepare the mac80211
ath patch dir and split it in the dedicated ath5k, ath9k, ath10k and ath11k
(empty for now).

From the patch series description:
Several security issues in the 802.11 implementations were found by
Mathy Vanhoef (New York University Abu Dhabi), who has published all
the details at
https://papers.mathyvanhoef.com/usenix2021.pdf
Specifically, the following CVEs were assigned:
* CVE-2020-24586 - Fragmentation cache not cleared on reconnection
* CVE-2020-24587 - Reassembling fragments encrypted under different
keys
* CVE-2020-24588 - Accepting non-SPP A-MSDU frames, which leads to
payload being parsed as an L2 frame under an
A-MSDU bit toggling attack
* CVE-2020-26139 - Forwarding EAPOL from unauthenticated sender
* CVE-2020-26140 - Accepting plaintext data frames in protected
networks
* CVE-2020-26141 - Not verifying TKIP MIC of fragmented frames
* CVE-2020-26142 - Processing fragmented frames as full frames
* CVE-2020-26143 - Accepting fragmented plaintext frames in
protected networks
* CVE-2020-26144 - Always accepting unencrypted A-MSDU frames that
start with RFC1042 header with EAPOL ethertype
* CVE-2020-26145 - Accepting plaintext broadcast fragments as full
frames
* CVE-2020-26146 - Reassembling encrypted fragments with non-consecutive
packet numbers
* CVE-2020-26147 - Reassembling mixed encrypted/plaintext fragments
In general, the scope of these attacks is that they may allow an
attacker to
* inject L2 frames that they can more or less control (depending on the
vulnerability and attack method) into an otherwise protected network;
* exfiltrate (some) network data under certain conditions, this is
specific to the fragmentation issues.
A subset of these issues is known to apply to the Linux IEEE 802.11
implementation (mac80211). Where it is affected, the attached patches
fix the issues, even if not all of them reference the exact CVE IDs.
In addition, driver and/or firmware updates may be necessary, as well
as potentially more fixes to mac80211, depending on how drivers are
using it.
Specifically, for Intel devices, firmware needs to be updated to the
most recently released versions (which was done without any reference
to the security issues) to address some of the vulnerabilities.
To have a single set of patches, I'm also including patches for the
ath10k and ath11k drivers here.
We currently don't have information about how other drivers are, if
at all, affected.

Missing braces in a macro were leading to badly working rates sometimes

When transmitting to a receiver in dynamic SMPS mode, all transmissions that
use multiple spatial streams need to be sent using CTS-to-self or RTS/CTS to
give the receiver's extra chains some time to wake up.
This fixes the tx rate getting stuck at <= MCS7 for some clients, especially
Intel ones, which make aggressive use of SMPS.

The removed patches were applied upstream.
This adapts ath10k-ct and mt76 to changed APIs.
nl80211.h in iw is updated to match the version from backports.

The removed patches were applied upstream.
Remove the 300-mac80211-optimize-skb-resizing.patch.
This patch was not applied upstream, but it conflicts with upstream
changes and needs bigger changes. It was applied with Felix to remove
this patch for now. It should be reworked and then send upstream later.

If the driver uses .sta_add, station entries are only uploaded after the sta
is in assoc state. Fix early station rate table updates by deferring them
until the sta has been uploaded

rt2800 olny gives you survey for current channel.
Survey-based ACS algorithms are failing to perform their job when working
with rt2800.
Make rt2800 save survey for every channel visited and be able to give away
that information.
There is a bug registred https://dev.archive.openwrt.org/ticket/19081 and
this patch solves the issue.

After the status rework, ieee80211_tx_status_ext is leaking un-acknowledged
packets for stations in powersave mode.
To fix this, move the code handling those packets from __ieee80211_tx_status
into ieee80211_tx_status_ext

The vendor driver does things differently based on what it finds in the
SoC's CHIP_VER register, which should tell whether this is MT7620N or
MT7620A (PKG) and probably also the revision (VER) and most likely
also something about the silicon implementer (ECO).
Introduce codepaths just like the ones in the vendor driver to handle
the different chips properly.
Some of those paths are most likely dead code and left-overs from FPGA
versions or early prototypes of the chip. It'd thus be great if people
can post their kernel logs, at least the line telling the chip version
and eco, so we know what's actually out there in the wild -- all I
could find is
[ 0.000000] SoC Type: Ralink MT7620A ver:2 eco:6
and
[ 0.000000] SoC Type: Ralink MT7620N ver:2 eco:6
which would make things easier, as then we really just need to know
whether it's MT7620N or MT7620A and not care about FPGA or prototypes
with ver <= 1 and eco <= 2.

When the nulldata frame was acked, the probe send count needs to be reset,
otherwise it will keep increasing until the connection is considered dead,
even though it fine.
