Subject: [PATCH] nl80211: add support for BSS coloring
This patch adds support for BSS color collisions to the wireless subsystem.
Add the required functionality to nl80211 that will notify about color
collisions, triggering the color change and notifying when it is completed.

Subject: [PATCH] mac80211: minstrel_ht: significantly redesign the rate
probing strategy
The biggest flaw in current minstrel_ht is the fact that it needs way too
many probing packets to be able to quickly find the best rate.
Depending on the wifi hardware and operating mode, this can significantly
reduce throughput when not operating at the highest available data rate.
In order to be able to significantly reduce the amount of rate sampling,
we need a much smarter selection of probing rates.
The new approach introduced by this patch maintains a limited set of
available rates to be tested during a statistics window.
They are split into distinct categories:
- MINSTREL_SAMPLE_TYPE_INC - incremental rate upgrade:
Pick the next rate group and find the first rate that is faster than
the current max. throughput rate
- MINSTREL_SAMPLE_TYPE_JUMP - random testing of higher rates:
Pick a random rate from the next group that is faster than the current
max throughput rate. This allows faster adaptation when the link changes
significantly
- MINSTREL_SAMPLE_TYPE_SLOW - test a rate between max_prob, max_tp2 and
max_tp in order to reduce the gap between them
In order to prioritize sampling, every 6 attempts are split into 3x INC,
2x JUMP, 1x SLOW.
Available rates are checked and refilled on every stats window update.
With this approach, we finally get a very small delta in throughput when
comparing setting the optimal data rate as a fixed rate vs normal rate
control operation.

Subject: [PATCH] mac80211: check per vif offload_flags in Tx path
offload_flags has been introduced to indicate encap status of each interface.
An interface can encap offload at runtime, or if it has some extra limitations
it can simply override the flags, so it's more flexible to check offload_flags
in Tx path.

Subject: [PATCH] rtlwifi: implement set_tim by update beacon content
Once beacon content is changed, we update the content to wifi card by
send_beacon_frame(). Then, STA with PS can wake up properly to receive its
packets.
Since we update beacon content to PCI wifi devices every beacon interval,
the only one usb device, 8192CU, needs to update beacon content when
mac80211 calling set_tim.

Subject: [PATCH] mac80211: add rx decapsulation offload support
This allows drivers to pass 802.3 frames to mac80211, with some restrictions:
- the skb must be passed with a valid sta
- fast-rx needs to be active for the sta
- monitor mode needs to be disabled
mac80211 will tell the driver when it is safe to enable rx decap offload for
a particular station.
In order to implement support, a driver must:
- call ieee80211_hw_set(hw, SUPPORTS_RX_DECAP_OFFLOAD)
- implement ops->sta_set_decap_offload
- mark 802.3 frames with RX_FLAG_8023
If it doesn't want to enable offload for some vif types, it can mask out
IEEE80211_OFFLOAD_DECAP_ENABLED in vif->offload_flags from within the
.add_interface or .update_vif_offload driver ops

Subject: [PATCH] mac80211: introduce individual TWT support in AP mode
Introduce TWT action frames parsing support to mac80211.
Currently just individual TWT agreement are support in AP mode.
Whenever the AP receives a TWT action frame from an associated client,
after performing sanity checks, it will notify the underlay driver with
requested parameters in order to check if they are supported and if there
is enough room for a new agreement. The driver is expected to set the
agreement result and report it to mac80211.
Drivers supporting this have two new callbacks:
- add_twt_setup (mandatory)
- twt_teardown_request (optional)
mac80211 will send an action frame reply according to the result
reported by the driver.

[use le16p_replace_bits(), minor cleanups, use (void *) casts,
fix to use ieee80211_get_he_iftype_cap() correctly]

define KernelPackage/rtl8xxxu/description
This is an alternative driver for various Realtek RTL8XXX
parts written to utilize the Linux mac80211 stack.
The driver is known to work with a number of RTL8723AU,
RL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU devices
This driver is under development and has a limited feature
set. In particular it does not yet support 40MHz channels
and power management. However it should have a smaller
memory footprint than the vendor drivers and benetifs
from the in kernel mac80211 stack.
It can coexist with drivers from drivers/staging/rtl8723au,
drivers/staging/rtl8192u, and drivers/net/wireless/rtlwifi,
but you will need to control which module you wish to load.
RTL8XXXU_UNTESTED is enabled
This option enables detection of Realtek 8723/8188/8191/8192 WiFi
USB devices which have not been tested directly by the driver
author or reported to be working by third parties.
Please report your results!

Subject: [PATCH] cfg80211: Add support to configure SAE PWE value to drivers
Add support to configure SAE PWE preference from userspace to drivers in
both AP and STA modes. This is needed for cases where the driver takes
care of Authentication frame processing (SME in the driver) so that
correct enforcement of the acceptable PWE derivation mechanism can be
performed.
The userspace applications can pass the sae_pwe value using the
NL80211_ATTR_SAE_PWE attribute in the NL80211_CMD_CONNECT and
NL80211_CMD_START_AP commands to the driver. This allows selection
between the hunting-and-pecking loop and hash-to-element options for PWE
derivation. For backwards compatibility, this new attribute is optional
and if not included, the driver is notified of the value being
unspecified.

Subject: [PATCH] mac80211: minstrel_ht: remove sample rate switching code for
constrained devices
This was added to mitigate the effects of too much sampling on devices that
use a static global fallback table instead of configurable multi-rate retry.
Now that the sampling algorithm is improved, this code path no longer performs
any better than the standard probing on affected devices.

From: Felix Fietkau <nbd@nbd.name>
Date: Tue, 29 Jun 2021 13:25:09 +0200
Subject: [PATCH] mac80211: fix starting aggregation sessions on mesh
interfaces
The logic for starting aggregation sessions was recently moved from minstrel_ht
to mac80211, into the subif tx handler just after the sta lookup.
Unfortunately this didn't work for mesh interfaces, since the sta lookup is
deferred until a much later point in time on those.
Fix this by also calling the aggregation check right after the deferred sta
lookup.
Fixes: 08a46c642001 ("mac80211: move A-MPDU session check from minstrel_ht to mac80211")

Subject: [PATCH] mac80211: minstrel_ht: reduce the need to sample slower
rates
In order to more gracefully be able to fall back to lower rates without too
much throughput fluctuations, initialize all untested rates below tested ones
to the maximum probabilty of higher rates.
Usually this leads to untested lower rates getting initialized with a
probability value of 100%, making them better candidates for fallback without
having to rely on random probing

Subject: [PATCH] mac80211: don't apply flow control on management frames
In some cases (depending on the driver, but it's true e.g. for
iwlwifi) we're using an internal TXQ for management packets,
mostly to simplify the code and to have a place to queue them.
However, it appears that in certain cases we can confuse the
code and management frames are dropped, which is certainly not
what we want.
Short-circuit the processing of management frames. To keep the
impact minimal, only put them on the frags queue and check the
tid == management only for doing that and to skip the airtime
fairness checks, if applicable.

Subject: [PATCH] mac80211: add support for BSS color change
The color change announcement is very similar to how CSA works where
we have an IE that includes a counter. When the counter hits 0, the new
color is applied via an updated beacon.
This patch makes the CSA counter functionality reusable, rather than
implementing it again. This also allows for future reuse incase support
for other counter IEs gets added.

Subject: [PATCH] mac80211: enable QoS support for nl80211 ctrl port
This patch unifies sending control port frames
over nl80211 and AF_PACKET sockets a little more.
Before this patch, EAPOL frames got QoS prioritization
only when using AF_PACKET sockets.
__ieee80211_select_queue only selects a QoS-enabled queue
for control port frames, when the control port protocol
is set correctly on the skb. For the AF_PACKET path this
works, but the nl80211 path used ETH_P_802_3.
Another check for injected frames in wme.c then prevented
the QoS TID to be copied in the frame.
In order to fix this, get rid of the frame injection marking
for nl80211 ctrl port and set the correct ethernet protocol.
Please note:
An erlier version of this path tried to prevent
frame aggregation for control port frames in order to speed up
the initial connection setup a little. This seemed to cause
issues on my older Intel dvm-based hardware, and was therefore
removed again. Future commits which try to reintroduce this
have to check carefully how hw behaves with aggregated and
non-aggregated traffic for the same TID.

Subject: [PATCH] nl80211: add common API to configure SAR power limitations
NL80211_CMD_SET_SAR_SPECS is added to configure SAR from
user space. NL80211_ATTR_SAR_SPEC is used to pass the SAR
power specification when used with NL80211_CMD_SET_SAR_SPECS.
Wireless driver needs to register SAR type, supported frequency
ranges to wiphy, so user space can query it. The index in
frequency range is used to specify which sub band the power
limitation applies to. The SAR type is for compatibility, so later
other SAR mechanism can be implemented without breaking the user
space SAR applications.
Normal process is user space queries the SAR capability, and
gets the index of supported frequency ranges and associates the
power limitation with this index and sends to kernel.
Here is an example of message send to kernel:

From: Felix Fietkau <nbd@nbd.name>
Date: Thu, 2 Dec 2021 13:30:05 +0100
Subject: [PATCH] mac80211: send ADDBA requests using the tid/queue of the
aggregation session
Sending them out on a different queue can cause a race condition where a
number of packets in the queue may be discarded by the receiver, because
the ADDBA request is sent too early.
This affects any driver with software A-MPDU setup which does not allocate
packet seqno in hardware on tx, regardless of whether iTXQ is used or not.
The only driver I've seen that explicitly deals with this issue internally
is mwl8k.

Subject: [PATCH] mac80211: use coarse boottime for airtime fairness code
The time values used by the airtime fairness code only need to be accurate
enough to cover station activity detection.
Using ktime_get_coarse_boottime_ns instead of ktime_get_boottime_ns will
drop the accuracy down to jiffies intervals, but at the same time saves
a lot of CPU cycles in a hot path

Subject: [PATCH] cfg80211: support immediate reconnect request hint
There are cases where it's necessary to disconnect, but an
immediate reconnection is desired. Support a hint to userspace
that this is the case, by including a new attribute in the
deauth or disassoc event.

From: Felix Fietkau <nbd@nbd.name>
Date: Wed, 25 Nov 2020 18:10:34 +0100
Subject: [PATCH] net/fq_impl: do not maintain a backlog-sorted list of
flows
A sorted flow list is only needed to drop packets in the biggest flow when
hitting the overmemory condition.
By scanning flows only when needed, we can avoid paying the cost of
maintaining the list under normal conditions
In order to avoid scanning lots of empty flows and touching too many cold
cache lines, a bitmap of flows with backlog is maintained
