-Subject: ath10k: improve tx status reporting
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-We use ieee80211_tx_status() to report each completed tx frame.
-Internally, this function calls sta_info_get_by_addrs(), what has a
-couple of drawbacks:
-1. additional station lookup causes a performance degradation;
-2. mac80211 can not properly account Ethernet encapsulated frames due
- to the inability to properly determine the destination (station) MAC
- address since ieee80211_tx_status() assumes the frame has a 802.11
- header.
-
-The latter is especially destructive if we want to use hardware frames
-encapsulation.
-
-To fix both of these issues, replace ieee80211_tx_status() with
-ieee80211_tx_status_ext() call and feed it station pointer from the tx
-queue associated with the transmitted frame.

-Subject: ath10k: htt_tx: do not interpret Eth frames as WiFi
-
-The xmit path for the Ethernet encapsulated frames become more or less
-usable since d740d8fd2439 ("ath10k: unify tx mode and dispatch"). This
-change reorganize the xmit path in a manageable way to properly support
-various tx modes, but misses that the Ethernet encapsulated frame is a
-special case. We do not have an IEEE 802.11 header at the begining of
-them. But the HTT Tx handler still interprets first bytes of each frame
-as an IEEE 802.11 Frame Control field.
-
-Than this code was copied by e62ee5c381c5 ("ath10k: Add support for
-htt_data_tx_desc_64 descriptor") and a2097d6444c3 ("ath10k: htt: High
-latency TX support") to another handlers. In fact the issue in the high
-latency (HL) handler was introduced by 83ac260151e7 ("ath10k: add mic
-bytes for pmf management packet").
-
-Ethernet encapsulated frame tx mode stay unused until 75d85fd9993c
-("ath10k: introduce basic tdls functionality") started using it for TDLS
-frames to avoid key selection issue in some firmwares.
-
-Trying to interpret the begining of an Ethernet encapsulated frame as an
-IEEE 802.11 header was not hurt us noticeably since we need to meet two
-conditions: (1) xmit should be performed towards a TDLS peer, and (2)
-the TDLS peer should have a specific OUI part of its MAC address. Looks
-like that the rareness in TDLS communications of OUIs that can be
-interpreted as an 802.11 management frame saves users from facing this
-issue earlier.
-
-Improve Ethernet tx mode support in the HTT Tx handler by avoiding
-interpreting its first bytes as an IEEE 802.11 header. While at it, make
-the ieee80211_hdr variable local to the code block that is guarded by
-!is_eth check. In this way, we clarify in which cases a frame can be
-interpreted as IEEE 802.11, and saves us from similar issues in the
-future.
-
-Credits: this change as part of xmit encapsulation offloading support
-was originally made by QCA and then submitted for inclusion by John
-Crispin [1]. But the whole work was not accepted due to the lack of a
-part for 64-bits descriptors [2]. Zhijun You then pointed this out to me
-in a reply to my initial RFC patch series. And I made this slightly
-reworked version that covered all the HTT Tx handler variants.

-Subject: ath10k: add encapsulation offloading support
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Frame encapsulation from Ethernet into the IEEE 802.11 frame format
-takes a considerable host CPU time on the xmit path. The firmware is
-able to do this operation for us, so enable encapsulation offloading for
-AP and Sta interface types to improve overall system performance.
-
-The driver is almost ready for encapsulation offloading support. There
-are only a few places where the driver assumes the frame format is IEEE
-802.11 that need to be fixed.
-
-Encapsulation offloading is currently disabled by default and the driver
-utilizes mac80211 encapsulation support. To activate offloading, the
-frame_mode=2 parameter should be passed during module loading.
-
-On a QCA9563+QCA9888-based access point in bridged mode, encapsulation
-offloading increases TCP 16-streams DL throughput from 365 to 396 mbps
-(+8%) and UDP DL throughput from 436 to 483 mbps (+11%).
-

-Subject: [PATCH] ath10k: support bus and device specific API 1 BDF selection
-
-Some ath10k IPQ40xx devices like the MikroTik hAP ac2 and ac3 require the
-BDF-s to be extracted from the device storage instead of shipping packaged
-API 2 BDF-s.
-
-This is required as MikroTik has started shipping boards that require BDF-s
-to be updated, as otherwise their WLAN performance really suffers.
-This is however impossible as the devices that require this are release
-under the same revision and its not possible to differentiate them from
-devices using the older BDF-s.
-
-In OpenWrt we are extracting the calibration data during runtime and we are
-able to extract the BDF-s in the same manner, however we cannot package the
-BDF-s to API 2 format on the fly and can only use API 1 to provide BDF-s on
-the fly.
-This is an issue as the ath10k driver explicitly looks only for the
-board.bin file and not for something like board-bus-device.bin like it does
-for pre-cal data.
-Due to this we have no way of providing correct BDF-s on the fly, so lets
-extend the ath10k driver to first look for BDF-s in the
-board-bus-device.bin format, for example: board-ahb-a800000.wifi.bin
-If that fails, look for the default board file name as defined previously.

-Subject: [PATCH] ath10k: fetch (pre-)calibration data via nvmem subsystem
-
-On most embedded ath10k devices (like range extenders,
-routers, accesspoints, ...) the calibration data is
-stored in a easily accessible MTD partitions named
-"ART", "caldata", "calibration", etc...
-
-Since commit 4b361cfa8624 ("mtd: core: add OTP nvmem provider support"):
-MTD partitions and portions of them can be specified
-as potential nvmem-cells which are accessible through
-the nvmem subsystem.
-
-This feature - together with an nvmem cell definition either
-in the platform data or via device-tree allows drivers to get
-the (pre-)calibration data which is required for initializing
-the WIFI.
-
-Tested with Netgear EX6150v2 (IPQ4018)

-Subject: ath9k: support DT ieee80211-freq-limit property to limit channels
-
-The common DT property can be used to limit the available channels
-but ath9k has to manually call wiphy_read_of_freq_limits().
-
-I would have put this into ath9k_of_init(). But it didn't work there.
-The reason is that in ath9k_of_init() the channels and bands are not yet
-registered in the wiphy struct. So there isn't any channel to flag as
-disabled.

-Subject: [PATCH] ath9k: fetch calibration data via nvmem subsystem
-
-On most embedded ath9k devices (like range extenders,
-routers, accesspoints, ...) the calibration data is
-stored in a MTD partitions named "ART", or "caldata"/
-"calibration".
-
-Ever since commit
-4b361cfa8624 ("mtd: core: add OTP nvmem provider support")
-all MTD partitions are all automatically available through
-the nvmem subsystem. This allows drivers like ath9k to read
-the necessary data without needing any userspace helpers
-that would do this extraction.

-Subject: [PATCH] ath9k: owl-loader: fetch pci init values through nvmem
-
-extends the owl loader to fetch important pci initialization
-values - which are stored together with the calibration data -
-through the nvmem subsystem.
-
-This allows for much faster WIFI/ath9k initializations on devices
-that do not require to perform any post-processing (like XOR'ing/
-reversal or unpacking) since no userspace helper is required.

-Move bbp_ready and rf_ready busy wait functions up in the code so they
-can more easily be used. Allow specifying register mask in rf_ready
-function which is useful for calibration routines which will be added

+ probability stats
+
+In some scenarios when there is a lot of fluctuation in packet error rates,
+rate switching can be amplified when the statistics get skewed by time slots
+with very few tries.
+Make the input data to the moving average more smooth by adding the
+success/attempts count from the last stats window as well. This has the
+advantage of smoothing the data without introducing any extra lag to sampling
+rates.
+This significantly improves rate stability on a strong test link subjected to
+periodic noise bursts generated with a SDR

+Subject: [PATCH] mac80211: minstrel_ht: rework rate downgrade code and
+ max_prob rate selection
+
+The current fallback code for fast rate switching on potentially failing rates
+is triggering too often if there is some strong noise on the channel. This can
+lead to wild fluctuations in the rate selection.
+Additionally, switching down to max_prob_rate can create a significant gap down
+in throughput, especially when using only 2 spatial streams, because max_prob_rate
+is limited to using fewer streams than the max_tp rates.
+In order to improve throughput without reducing reliability too much, use the
+rate downgrade code for the max_prob_rate only, and allow the non-downgraded
+max_prob_rate to use as many spatial streams as the max_tp rates

-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] mac80211: add support for restricting netdev features per vif
+
+This can be used to selectively disable feature flags for checksum offload,
+scatter/gather or GSO by changing vif->netdev_features.
+Removing features from vif->netdev_features does not affect the netdev
+features themselves, but instead fixes up skbs in the tx path so that the
+offloads are not needed in the driver.
+
+Aside from making it easier to deal with vif type based hardware limitations,
+this also makes it possible to optimize performance on hardware without native
+GSO support by declaring GSO support in hw->netdev_features and removing it
+from vif->netdev_features. This allows mac80211 to handle GSO segmentation
+after the sta lookup, but before itxq enqueue, thus reducing the number of
+unnecessary sta lookups, as well as some other per-packet processing.

-Subject: [PATCH] mac80211: minstrel_ht: reduce fluctuations in rate
- probability stats
-
-In some scenarios when there is a lot of fluctuation in packet error rates,
-rate switching can be amplified when the statistics get skewed by time slots
-with very few tries.
-Make the input data to the moving average more smooth by adding the
-success/attempts count from the last stats window as well. This has the
-advantage of smoothing the data without introducing any extra lag to sampling
-rates.
-This significantly improves rate stability on a strong test link subjected to
-periodic noise bursts generated with a SDR

-Subject: [PATCH] mac80211: minstrel_ht: rework rate downgrade code and
- max_prob rate selection
-
-The current fallback code for fast rate switching on potentially failing rates
-is triggering too often if there is some strong noise on the channel. This can
-lead to wild fluctuations in the rate selection.
-Additionally, switching down to max_prob_rate can create a significant gap down
-in throughput, especially when using only 2 spatial streams, because max_prob_rate
-is limited to using fewer streams than the max_tp rates.
-In order to improve throughput without reducing reliability too much, use the
-rate downgrade code for the max_prob_rate only, and allow the non-downgraded
-max_prob_rate to use as many spatial streams as the max_tp rates

-Subject: [PATCH] cfg80211: implement APIs for dedicated radar detection HW
-
-If a dedicated (off-channel) radar detection hardware (chain)
-is available in the hardware/driver, allow this to be used by
-calling the NL80211_CMD_RADAR_DETECT command with a new flag
-attribute requesting off-channel radar detection is used.
-
-Offchannel CAC (channel availability check) avoids the CAC
-downtime when switching to a radar channel or when turning on
-the AP.
-
-Drivers advertise support for this using the new feature flag
-NL80211_EXT_FEATURE_RADAR_OFFCHAN.

-Subject: [PATCH] cfg80211: move offchan_cac_event to a dedicated work
-
-In order to make cfg80211_offchan_cac_abort() (renamed from
-cfg80211_offchan_cac_event) callable in other contexts and
-without so much locking restrictions, make it trigger a new
-work instead of operating directly.
-
-Do some other renames while at it to clarify.

-If necessary schedule offchan_cac_abort_wk work in cfg80211_radar_event
-routine adding offchan parameter to cfg80211_radar_event signature.
-Rename cfg80211_radar_event in __cfg80211_radar_event and introduce
-the two following inline helpers:
-- cfg80211_radar_event
-- cfg80211_offchan_radar_event
-Doing so the drv will not need to run cfg80211_offchan_cac_abort() after

-Subject: [PATCH] cfg80211: rename offchannel_chain structs to background_chain
- to avoid confusion with ETSI standard
-
-ETSI standard defines "Offchannel CAC" as:
-"Off-Channel CAC is performed by a number of non-continuous checks
-spread over a period in time. This period, which is required to
-determine the presence of radar signals, is defined as the Off-Channel
-CAC Time..
-Minimum Off-Channel CAC Time 6 minutes and Maximum Off-Channel CAC Time
-4 hours..".
-mac80211 implementation refers to a dedicated hw chain used for continuous
-radar monitoring. Rename offchannel_* references to background_* in
-order to avoid confusion with ETSI standard.

-Subject: [PATCH] mac80211: MBSSID support in interface handling
-
-Configure multiple BSSID and enhanced multi-BSSID advertisement (EMA)
-parameters in mac80211 for AP mode.
-
-For each interface, 'mbssid_tx_vif' points to the transmitting interface of
-the MBSSID set. The pointer is set to NULL if MBSSID is disabled.
-
-Function ieee80211_stop() is modified to always bring down all the
-non-transmitting interfaces first and the transmitting interface last.

-
-When a vif is being removed and sdata->bss is cleared, __ieee80211_wake_txqs
-can still be called on it, which crashes as soon as sdata->bss is being
-dereferenced.
-To fix this properly, check for SDATA_STATE_RUNNING before waking queues,
-and take the fq lock when setting it (to ensure that __ieee80211_wake_txqs

-Subject: [PATCH] mac80211: switch airtime fairness back to deficit round-robin
- scheduling
-
-This reverts commits 6a789ba679d652587532cec2a0e0274fda172f3b and
-2433647bc8d983a543e7d31b41ca2de1c7e2c198.
-
-The virtual time scheduler code has a number of issues:
-- queues slowed down by hardware/firmware powersave handling were not properly
- handled.
-- on ath10k in push-pull mode, tx queues that the driver tries to pull from
- were starved, causing excessive latency
-- delay between tx enqueue and reported airtime use were causing excessively
- bursty tx behavior
-
-The bursty behavior may also be present on the round-robin scheduler, but there
-it is much easier to fix without introducing additional regressions

--/* A problem when trying to enforce airtime fairness is that we want to divide

-- * the instantaneous queue state of stations doesn't work, as queues tend to
-- * oscillate very quickly between empty and occupied, leading to the scheduler
-- * thinking only a single station is active when deciding whether to allow
-- * transmission (and thus not throttling correctly).
-- *
-- * To fix this we use a timer-based notion of activity: a station is considered
-- * active if it has been scheduled within the last 100 ms; we keep a separate
-- * list of all the stations considered active in this manner, and lazily update
-- * the total weight of active stations from this list (filtering the stations in
-- * the list by their 'last active' time).
-- *
-- * We add one additional safeguard to guard against stations that manage to get
-- * scheduled every 100 ms but don't transmit a lot of data, and thus don't use
-- * up any airtime. Such stations would be able to get priority for an extended
-- * period of time if they do start transmitting at full capacity again, and so
-- * we add an explicit maximum for how far behind a station is allowed to fall in
-- * the virtual airtime domain. This limit is set to a relatively high value of
-- * 20 ms because the main mechanism for catching up idle stations is the active
-- * state as described above; i.e., the hard limit should only be hit in
-- * pathological cases.

- deficit
-
-When queueing packets for a station, deficit only gets added once the packets
-have been transmitted, which could be much later. During that time, a lot of
-temporary unfairness could happen, which could lead to bursty behavior.
-Fix this by subtracting the aql_tx_pending when checking the deficit in tx
-scheduling.

-Subject: [PATCH] mac80211: add a per-PHY AQL limit to improve fairness
-
-In order to maintain fairness, the amount of queueing needs to be limited
-beyond the simple per-station AQL budget, otherwise the driver can simply
-repeatedly do scheduling rounds until all queues that have not used their
-AQL budget become eligble.
-
-To be conservative, use the high AQL limit for the first txq and add half
-of the low AQL for each subsequent queue.

-Subject: [PATCH] mac80211: exclude multicast packets from AQL pending airtime
-
-In AP mode, multicast traffic is handled very differently from normal traffic,
-especially if at least one client is in powersave mode.
-This means that multicast packets can be buffered a lot longer than normal
-unicast packets, and can eat up the AQL budget very quickly because of the low
-data rate.
-Along with the recent change to maintain a global PHY AQL limit, this can lead
-to significant latency spikes for unicast traffic.
-
-Since queueing multicast to hardware is currently not constrained by AQL limits
-anyway, let's just exclude it from the AQL pending airtime calculation entirely.

-Subject: [PATCH] mac80211: Fix deadlock: Don't start TX while holding
- fq->lock
-
-ieee80211_txq_purge() calls fq_tin_reset() and
-ieee80211_purge_tx_queue(); Both are then calling
-ieee80211_free_txskb(). Which can decide to TX the skb again.
-
-There are at least two ways to get a deadlock:
-
-1) When we have a TDLS teardown packet queued in either tin or frags
- ieee80211_tdls_td_tx_handle() will call ieee80211_subif_start_xmit()
- while we still hold fq->lock. ieee80211_txq_enqueue() will thus
- deadlock.
-
-2) A variant of the above happens if aggregation is up and running:
- In that case ieee80211_iface_work() will deadlock with the original
- task: The original tasks already holds fq->lock and tries to get
- sta->lock after kicking off ieee80211_iface_work(). But the worker
- can get sta->lock prior to the original task and will then spin for
- fq->lock.
-
-Avoid these deadlocks by not sending out any skbs when called via
-ieee80211_free_txskb().

-Subject: [PATCH] mac80211: Ensure vif queues are operational after start
-
-Make sure local->queue_stop_reasons and vif.txqs_stopped stay in sync.
-
-When a new vif is created the queues may end up in an inconsistent state
-and be inoperable:
-Communication not using iTXQ will work, allowing to e.g. complete the
-association. But the 4-way handshake will time out. The sta will not
-send out any skbs queued in iTXQs.
-
-All normal attempts to start the queues will fail when reaching this
-state.
-local->queue_stop_reasons will have marked all queues as operational but
-vif.txqs_stopped will still be set, creating an inconsistent internal
-state.
-
-In reality this seems to be race between the mac80211 function
-ieee80211_do_open() setting SDATA_STATE_RUNNING and the wake_txqs_tasklet:
-Depending on the driver and the timing the queues may end up to be
-operational or not.

-Subject: [PATCH] wifi: mac80211: fix mesh airtime link metric estimating
-
-ieee80211s_update_metric function uses sta_set_rate_info_tx
-function to get struct rate_info data from ieee80211_tx_rate
-struct, present in ieee80211_sta->deflink.tx_stats. However,
-drivers can skip tx rate calculation by setting rate idx as
--1. Such drivers provides rate_info directly and hence
-ieee80211s metric is updated incorrectly since ieee80211_tx_rate
-has inconsistent data.
-
-Add fix to use rate_info directly if present instead of
-sta_set_rate_info_tx for updating ieee80211s metric.

-Subject: [PATCH] mac80211: introduce BSS color collision detection
-
-Add ieee80211_rx_check_bss_color_collision routine in order to introduce
-BSS color collision detection in mac80211 if it is not supported in HW/FW
-(e.g. for mt7915 chipset).
-Add IEEE80211_HW_DETECTS_COLOR_COLLISION flag to let the driver notify
-BSS color collision detection is supported in HW/FW. Set this for ath11k
-which apparently didn't need this code.

-Subject: [PATCH] mac80211: add support for restricting netdev features per vif
-
-This can be used to selectively disable feature flags for checksum offload,
-scatter/gather or GSO by changing vif->netdev_features.
-Removing features from vif->netdev_features does not affect the netdev
-features themselves, but instead fixes up skbs in the tx path so that the
-offloads are not needed in the driver.
-
-Aside from making it easier to deal with vif type based hardware limitations,
-this also makes it possible to optimize performance on hardware without native
-GSO support by declaring GSO support in hw->netdev_features and removing it
-from vif->netdev_features. This allows mac80211 to handle GSO segmentation
-after the sta lookup, but before itxq enqueue, thus reducing the number of
-unnecessary sta lookups, as well as some other per-packet processing.

-- * This feature is applicable to drivers running in AP mode.

-- * FILS shared key crypto offload can be advertised by drivers by setting

-- * FILS shared key crypto offload should be able to encrypt and decrypt

-- * With this capability, for FILS key derivation, drivers depend on userspace.
-- *
-- * After FILS key derivation, userspace shares the FILS AAD details with the
-- * driver and the driver stores the same to use in decryption of association
-- * request and in encryption of association response. The below parameters
-- * should be given to the driver in %NL80211_CMD_SET_FILS_AAD.
-- * %NL80211_ATTR_MAC - STA MAC address, used for storing FILS AAD per STA

-- * %NL80211_ATTR_FILS_NONCES - Used for encryption or decryption
