-Subject: [PATCH] mac80211: add an intermediate software queue implementation
-
-This allows drivers to request per-vif and per-sta-tid queues from which
-they can pull frames. This makes it easier to keep the hardware queues
-short, and to improve fairness between clients and vifs.
-
-The task of scheduling packet transmission is left up to the driver -
-queueing is controlled by mac80211. Drivers can only dequeue packets by
-calling ieee80211_tx_dequeue. This makes it possible to add active queue
-management later without changing drivers using this code.
-
-This can also be used as a starting point to implement A-MSDU
-aggregation in a way that does not add artificially induced latency.

-+ * DOC: mac80211 software tx queueing
-+ *
-+ * mac80211 provides an optional intermediate queueing implementation designed
-+ * to allow the driver to keep hardware queues short and provide some fairness
-+ * between different stations/interfaces.
-+ * In this model, the driver pulls data frames from the mac80211 queue instead
-+ * of letting mac80211 push them via drv_tx().
-+ * Other frames (e.g. control or management) are still pushed using drv_tx().
-+ *
-+ * Drivers indicate that they use this model by implementing the .wake_tx_queue
-+ * driver operation.
-+ *
-+ * Intermediate queues (struct ieee80211_txq) are kept per-sta per-tid, with a
-+ * single per-vif queue for multicast data frames.
-+ *
-+ * The driver is expected to initialize its private per-queue data for stations
-+ * and interfaces in the .add_interface and .sta_add ops.
-+ *
-+ * The driver can't access the queue directly. To dequeue a frame, it calls
-+ * ieee80211_tx_dequeue(). Whenever mac80211 adds a new frame to a queue, it
-+ * calls the .wake_tx_queue driver op.
-+ *
-+ * For AP powersave TIM handling, the driver only needs to indicate if it has
-+ * buffered packets in the driver specific data structures by calling
-+ * ieee80211_sta_set_buffered(). For frames buffered in the ieee80211_txq
-+ * struct, mac80211 sets the appropriate TIM PVB bits and calls
-+ * .release_buffered_frames().
-+ * In that callback the driver is therefore expected to release its own
-+ * buffered frames and afterwards also frames from the ieee80211_txq (obtained
-+ * via the usual ieee80211_tx_dequeue).

-Subject: [PATCH] mac80211: lock rate control
-
-Both minstrel (reported by Sven Eckelmann) and the iwlwifi rate
-control aren't properly taking concurrency into account. It's
-likely that the same is true for other rate control algorithms.
-
-In the case of minstrel this manifests itself in crashes when an
-update and other data access are run concurrently, for example
-when the stations change bandwidth or similar. In iwlwifi, this
-can cause firmware crashes.
-
-Since fixing all rate control algorithms will be very difficult,
-just provide locking for invocations. This protects the internal
-data structures the algorithms maintain.
-
-I've manipulated hostapd to test this, by having it change its
-advertised bandwidth roughly ever 150ms. At the same time, I'm
-running a flood ping between the client and the AP, which causes
-this race of update vs. get_rate/status to easily happen on the
-client. With this change, the system survives this test.

+Subject: [PATCH] ath: DFS - limit number of potential PRI sequences
+
+In the PRI detector, after the current radar pulse
+has been checked agains existing PRI sequences, it
+is considered as part of a new potential sequence.
+
+Previously, the condition to accept a new sequence
+was to have at least the same number of pulses as
+the longest matching sequence. This was wrong,
+since it led to duplicates of PRI sequences.
+
+This patch changes the acceptance criteria for new
+potential sequences from 'at least' to 'more than'
+the longest existing.
+
+Detection performance remains unaffected, while
+the number of PRI sequences accounted at runtime
+(and with it CPU load) is reduced by up to 50%.

+Subject: [PATCH] ath9k: DFS - add pulse chirp detection for FCC
+
+FCC long pulse radar (type 5) requires pulses to be
+checked for chirping. This patch implements chirp
+detection based on the FFT data provided for long
+pulses.
+
+A chirp is detected when a set of criteria defined
+by FCC pulse characteristics is met, including
+* have at least 4 FFT samples
+* max_bin index moves equidistantly between samples
+* the gradient is within defined range
+
+The chirp detection has been tested with reference
+radar generating devices and proved to work reliably.

-Subject: [PATCH] ath5k: channel change fix
-
-ath5k updates the channel pointer and after that it stops the Rx logic
-and apply channel to HW. In case of channel switch, such sequence
-creates a small window when a frame, which is received on the old
-channel is considered as a frame received on the new one.
-
-The most notable consequence of this situation occurs during the switch
-from 2 GHz band (CCK+OFDM) to the 5GHz band (OFDM-only). Frame received
-with CCK rate, e.g. beacon received at the 1mbps, causes the following
-warning:

-
-The easiest way to reproduce this warning is to run scan with dualband
-NIC in noisy environments, when the channel 11 runs multiple APs. In my
-tests if the APs num >= 12, the warning appears in the first few
-seconds of scanning.
-
-In order to fix this, the Rx disable code moved to a higher level and
-placed before the channel pointer update. This is also makes the code a
-bit more symmetrical, since we disable and enable the Rx in the same
-function.
-
-In fact, at the pointer update time new frames should not appear,
-because interrupt generation at this point should already be disabled.
-The next patch should address this issue.

+Subject: [PATCH] ath9k: make DMA stop related messages debug-only
+
+A long time ago, ath9k had issues during reset where the DMA engine
+would stay active and could potentially corrupt memory.
+To debug those issues, the driver would print warnings whenever they
+occur.
+
+Nowadays, these issues are gone and the primary cause of these messages
+is if the MAC is stuck during reset or busy processing a long
+transmission. This is fairly harmless, yet these messages continue to
+worry users.
+
+To reduce the number of bogus bug reports, turn these messages into
+debug messages and count their occurence in the "reset" debugfs file.

-Subject: [PATCH] ath5k: fix reset race
-
-To prepare for reset ath5k should finish all asynchronous tasks. At
-first, it disables the interrupt generation, then it waits for the
-interrupt handler and tasklets completion, and then proceeds to the HW
-configuration update. But it does not consider that the interrupt
-handler or tasklet re-enables the interrupt generation. And we fall in a
-situation when ath5k assumes that interrupts are disabled, but it is
-not.
-
-This can lead to different consequences, such as reception of the frame,
-when we do not expect it. Under certain circumstances, this can lead to
-the following warning:
-
- WARNING: at ath5k/base.c:589 ath5k_tasklet_rx+0x318/0x6ec [ath5k]()

-
-Fix this issue by adding a new status flag, which forbids to re-enable
-the interrupt generation until the HW configuration is completed.
-
-Note: previous patch, which reorders the Rx disable code helps to avoid
-the above warning, but not fixes the root cause of unexpected frame
-receiving.

-Subject: [PATCH] mac80211: don't look up destination station twice
-
-There's no need to look up the destination station twice while
-building the 802.11 header for a given frame if the frame will
-actually be transmitted to the station we initially looked up.
-
-This happens for 4-addr VLAN interfaces and TDLS connections, which
-both directly send the frame to the station they looked up, though
-in the case of TDLS some station conditions need to be checked.
-
-To avoid that, add a variable indicating that we've looked up the
-station that the frame is going to be transmitted to, and avoid the
-lookup/flag checking if it already has been done.
-
-In the TDLS case, also move the authorized/wme_sta flag assignment
-to the correct place, i.e. only when that station is really used.
-Before this change, the new lookup should always have succeeded so
-that the potentially erroneous data would be overwritten.

-
-Instead of looking up the destination station twice in the TX path
-(first to build the header, and then for control processing), save
-it when building the header and use it later in the TX path.
-
-To avoid having to look up the station in the many callers, allow

-Subject: [PATCH] brcmfmac: Fix race condition in msgbuf ioctl processing.
-
-Msgbuf is using a wait_event_timeout to wait for the response on
-an ioctl. The wakeup routine uses waitqueue_active to see if
-wait_event_timeout has been called. There is a chance that the
-response arrives before wait_event_timeout is called, this
-will result in situation that wait_event_timeout never gets
-woken again and assumed result will be a timeout. This patch
-removes that errornous situation by always setting the
-ctl_completed var before checking for queue active.

-Subject: [PATCH] ath9k_htc: add new WMI_REG_RMW_CMDID command
-
-Since usb bus add extra delay on each request, a command
-with read + write requests is too expensive. We can dramtically
-reduce usb load by moving this command to firmware.
-
-In my tests, this patch will reduce channel scan time
-for about 5-10 seconds.

-On removal of SDIO card both functions of card will be getting
-a remove call. When the first is hanging in ctrl frame xmit then
-the second will cause oops. This patch fixes the xmit ctrl
-handling in case of serious errors and also limits the handling

-Subject: [PATCH] brcmfmac: Fix possible race-condition.
-
-SDIO is using a "shared" variable to handoff ctl frames to DPC
-and to see when they are done. In a timeout situation this can
-lead to erroneous situation where DPC started to handle the ctl
-frame while the timeout expired. This patch will fix this by
-adding locking around the shared variable.

-The watchdog timer is used to put the device in a low-power mode when
-it is idle for some time. This timer is stopped during that mode and
-should be restarted upon activity. This has been broken by commit

-
-Several host controllers supporting runtime-pm are causing issues
-with our sdio wireless cards because they disable the sdio interrupt
-upon going into runtime suspend. This patch avoids that by doing
-a pm_runtime_forbid() call during the probe. Tested with Sony Vaio

-
-The BCM43362 firmware falsely reports it is capable of providing
-MBSS. As a result AP mode no longer works for this device. Therefor
-disable MBSS in the driver for this chipset.

-Subject: [PATCH] brcmfmac: use static superset of channels for wiphy
- bands
-
-The driver was constructing a list of channels per wiphy band
-by querying the device. This list is not what the hardware is
-able to do as it is already filtered by the country setting in
-the device. As user-space may change the country this would
-require updating the channel list which is not recommended [1].
-This patch introduces a superset of channels. The individual
-channels are disabled appropriately by querying the device.

-Subject: [PATCH] brcmfmac: process interrupt regardless sdiod state
-
-When the sdio bus state is not ready to process we abort the
-interrupt service routine. This is not wanted as it keeps the
-interrupt source active. Better clear the interrupt source.

-Subject: [PATCH] brcmfmac: fix sdio suspend and resume
-
-commit 330b4e4be937 ("brcmfmac: Add wowl support for SDIO devices.")
-changed the behaviour by removing the MMC_PM_KEEP_POWER flag for
-non-wowl scenario, which needs to be restored. Another necessary
-change is to mark the card as being non-removable. With this in place
-the suspend resume test passes successfully doing:
-
- # echo devices > /sys/power/pm_test
- # echo mem > /sys/power/state
-
-Note that power may still be switched off when system is going
-in S3 state.

- nvram.
-
-With PCIE it is possible to support multiple devices with the
-same device type. They all load the same nvram file. In order to
-support this the nvram can specify which part of the nvram is
-for which pcie device. This patch adds support for these new
-types of nvram files.

-Subject: [PATCH] brcmfmac: Improve throughput by scheduling msbug flow worker.
-
-The tx flow worker in msgbuf gets scheduled at tx till a certain
-threshold has been reached. Then the tx completes will take over
-the scheduling. When amsdu and ampdu is used the frames are
-transferred wireless in a very bulky fashion, in combination
-with this scheduling algorithm and buffer limiters in the stack
-this can result in limited throughput. This change causes the
-flow worker to be scheduled more frequently from tx.

-Subject: [PATCH] brcmfmac: add support for dma indices feature
-
-PCIe full dongle firmware can support a dma indices feature with which
-firmware can update/fetch the read/write indices of message buffer
-rings on both host to dongle and dongle to host directions. The support is
-announced by firmware through shared flags.

-Comparing NVRAM entry with a full filtering string is simpler than

-This fixes brcmfmac dealing with NVRAM coming from platform e.g. from a

-of \n which caused ignoring whole content after the first "comment".
-While platform NVRAM doesn't usually contain comments, we switch to

-Subject: [PATCH] brcmfmac: support NVRAMs containing pci devpaths (instead of
- pcie)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Recently Broadcom added support for NVRAMs with entries for multiple
-PCIe devices. One of the supported formats is based on prefixes defined
-like: devpath0=pcie/1/4/ and entries like 0:foo=bar 0:baz=qux etc.
-
-Unfortunately there are also a bit older devices using different way of
-defining prefixes, e.g. SmartRG SR400ac (2 x BCM43602) with entries:
-devpath0=pci/1/1/
-devpath1=pci/2/1
-Broadcom stated this old format will never be used/supported by brcmfmac
-but given the simplicity of this patch I'll insist on supporting it.

-Subject: [PATCH] b43: fix support for 14e4:4321 PCI dev with BCM4321 chipset
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-It seems Broadcom released two devices with conflicting device id. There
-are for sure 14e4:4321 PCI devices with BCM4321 (N-PHY) chipset, they
-can be found in routers, e.g. Netgear WNR834Bv2. However, according to
-Broadcom public sources 0x4321 is also used for 5 GHz BCM4306 (G-PHY).
-It's unsure if they meant PCI device id, or "virtual" id (from SPROM).
-To distinguish these devices lets check PHY type (G vs. N).

-Subject: [PATCH] brcmfmac: Update msgbuf read pointer quicker.
-
-On device to host data using msgbuf the read pointer gets updated
-once all data is processed. Updating this pointer more frequently
-allows the firmware to add more data quicker. This will result in
-slightly higher and more stable throughput on CPU bounded host
-processors.

-Subject: [PATCH] brcmfmac: remove watchdog reset from
- brcmf_pcie_buscoreprep()
-
-The watchdog reset as done in brcmf_pcie_buscoreprep() is not
-sufficient. It needs to modify PCIe core registers as well
-which is properly done by brcmf_pcie_reset_device() after the
-chip recognition is done. So the faulty watchdog reset can be
-removed as it was causing driver reload to fail and hang the
-system requiring a power-cycle. Instead the call to to the
-brcmf_pcie_reset_device() function is done twice in the unload.

-Subject: [PATCH] brcmfmac: rework .get_station() callback
-
-The .get_station() cfg80211 callback is used in several scenarios. In
-managed mode it can obtain information about the access-point and its
-BSS parameters. In managed mode it can also obtain information about
-TDLS peers. In AP mode it can obtain information about connected
-clients.

-Subject: [PATCH] ath9k: make DMA stop related messages debug-only
-
-A long time ago, ath9k had issues during reset where the DMA engine
-would stay active and could potentially corrupt memory.
-To debug those issues, the driver would print warnings whenever they
-occur.
-
-Nowadays, these issues are gone and the primary cause of these messages
-is if the MAC is stuck during reset or busy processing a long
-transmission. This is fairly harmless, yet these messages continue to
-worry users.
-
-To reduce the number of bogus bug reports, turn these messages into
-debug messages and count their occurence in the "reset" debugfs file.

-When running with DT, we no longer have a board file that can set up the
-platform data for wlcore. Allow this data to be passed from DT.
-
-Since some platforms use a gpio-irq, add support for passing either the
-irq number or the gpio number. For the latter case, the driver will
-request the gpio and convert it to the irq number. If an irq is
-specified, it'll be used as is.
-
-[Arik - the pdev_data pointer does not belong to us and is freed when
-the device is released. Dereference to our private data first.]
