+
+In some cases, the channel might be busy enough that an ath9k AP's
+response to PS-Poll frames might be too slow and the station has already
+gone to sleep. To avoid wasting too much airtime on this, limit the
+number of retries on such frames and ensure that no sample rate gets
+used.

-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] ath10k: Delay device access after cold reset
+
+It is observed that during cold reset pcie access right
+after a write operation to SOC_GLOBAL_RESET_ADDRESS causes
+Data Bus Error and system hard lockup. The reason
+for bus error is that pcie needs some time to get
+back to stable state for any transaction during cold reset. Add
+delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
+to fix this issue.

-
-The chip reports radar pulses on extension channel
-even if operating in HT20 mode. This patch adds a
-sanity check for HT40 mode before it feeds pulses

-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] 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] ath10k: Delay device access after cold reset
-
-It is observed that during cold reset pcie access right
-after a write operation to SOC_GLOBAL_RESET_ADDRESS causes
-Data Bus Error and system hard lockup. The reason
-for bus error is that pcie needs some time to get
-back to stable state for any transaction during cold reset. Add
-delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
-to fix this issue.

+Subject: [PATCH] ath9k: Fix NF CCA limits for AR9287 and AR9227
+
+The FreeBSD driver [0] uses the same 2G values as for the AR9280 chips.
+Using the same values in ath9k results in much better throughput for me.
+
+Before this patch I had a huge amount of packet loss (sometimes up to
+40%) and the max transfer speed was somewhere around 5Mbit/s. With this
+patch applied I have zero packet loss and ten times the throughput.
+My device uses a AR9227 which is the PCI variant of the AR9287.

-Subject: [PATCH] cfg80211: use RTNL locked reg_can_beacon for IR-relaxation
-
-The RTNL is required to check for IR-relaxation conditions that allow
-more channels to beacon. Export an RTNL locked version of reg_can_beacon
-and use it where possible in AP/STA interface type flows, where
-IR-relaxation may be applicable.

-Subject: [PATCH] brcmfmac: set wiphy's addresses to provide valid MACs
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Broadcom's firmware requires every BSS to use MAC address with unique
-last few bits. The amount of bits may depend on a particular firmware,
-it was verified to be 2 for BCM43602 one.
-If this condition won't be fulfilled firmware will reject such MAC:
-brcmfmac: _brcmf_set_mac_address: Setting cur_etheraddr failed, -52
-
-We don't want to simply set addr_mask as it would also disallow using
-locally administrated bit. Instead let's build a list of addresses
-manually enabling 0x2 bit for extra interfaces.
