+Subject: [PATCH] ath10k: handle tdls peer events
+
+Handle tdls peer events from the target. TDLS events for the peer
+could be discover, teardown, etc. As of now, adding the logic to
+handle tdls teardown events alone.
+
+Teardown due to peer traffic indication(PTR) timeout is one such
+teardown event from the target.
+
+Tested this change on QCA9888 with 10.4-3.5.1-00018 fw version.

+Subject: [PATCH] ath10k: wmi: modify svc bitmap parsing for wcn3990
+
+Due to the limitation of wmi tlv parsing logic, if there are
+two parameters in a wmi event with same tlv tag, we can get only
+the last value, as it overwrites the prev value of the same tlv tag.
+
+The service ready event in wcn3990 contains two parameters of the
+same tag UINT32, due to which the svc bitmap is overwritten with the
+DBS support parameter.
+
+Refactor the service ready event parsing to allow parsing two tlv
+of the same tag UINT32 for wcn3990.

+Subject: [PATCH] ath10k: Fix kernel panic while using worker
+ (ath10k_sta_rc_update_wk)
+
+When attempt to run worker (ath10k_sta_rc_update_wk) after the station object
+(ieee80211_sta) delete will trigger the kernel panic.
+
+This problem arise in AP + Mesh configuration, Where the current node AP VAP
+and neighbor node mesh VAP MAC address are same. When the current mesh node
+try to establish the mesh link with neighbor node, driver peer creation for
+the neighbor mesh node fails due to duplication MAC address. Already the AP
+VAP created with same MAC address.
+
+It is caused by the following scenario steps.
+
+Steps:
+1. In above condition, ath10k driver sta_state callback (ath10k_sta_state)
+ fails to do the state change for a station from IEEE80211_STA_NOTEXIST
+ to IEEE80211_STA_NONE due to peer creation fails. Sta_state callback is
+ called from ieee80211_add_station() to handle the new station
+ (neighbor mesh node) request from the wpa_supplicant.
+2. Concurrently ath10k receive the sta_rc_update callback notification from
+ the mesh_neighbour_update() to handle the beacon frames of the above
+ neighbor mesh node. since its atomic callback, ath10k driver queue the
+ work (ath10k_sta_rc_update_wk) to handle rc update.
+3. Due to driver sta_state callback fails (step 1), mac80211 free the station
+ object.
+4. When the worker (ath10k_sta_rc_update_wk) scheduled to run, it will access
+ the station object which is already deleted. so it will trigger kernel
+ panic.
+
+Added the peer exist check in sta_rc_update callback before queue the work.
+

+Subject: [PATCH] ath10k: fix kernel panic while reading tpc_stats
+
+When attempt to read tpc_stats for the chipsets which support
+more than 3 tx chain will trigger kernel panic(kernel stack is corrupted)
+due to writing values on rate_code array out of range.
+This patch changes the array size depends on the WMI_TPC_TX_N_CHAIN and
+added check to avoid write values on the array if the num tx chain
+get in tpc config event is greater than WMI_TPC_TX_N_CHAIN.
+
+Tested on QCA9984 with firmware-5.bin_10.4-3.5.3-00057

+Subject: [PATCH] ath: add support to get the detected radar specifications
+
+This enables ath10k/ath9k drivers to collect the specifications of the
+radar type once it is detected by the dfs pattern detector unit.
+Usage of the collected info is specific to driver implementation.
+For example, collected radar info could be used by the host driver
+to send to co-processors for additional processing/validation.
+
+Note: 'radar_detector_specs' data containing the specifications of
+different radar types which was private within dfs_pattern_detector/
+dfs_pri_detector is now shared with drivers as well for making use
+of this information.

+Subject: [PATCH] ath10k: DFS Host Confirmation
+
+In the 10.4-3.6 firmware branch there's a new DFS Host confirmation
+feature which is advertised using WMI_SERVICE_HOST_DFS_CHECK_SUPPORT flag.
+
+This new features enables the ath10k host to send information to the
+firmware on the specifications of detected radar type. This allows the
+firmware to validate if the host's radar pattern detector unit is
+operational and check if the radar information shared by host matches
+the radar pulses sent as phy error events from firmware. If the check
+fails the firmware won't allow use of DFS channels on AP mode when using
+FCC regulatory region.
+
+Hence this patch is mandatory when using a firmware from 10.4-3.6 branch.
+Else, DFS channels on FCC regions cannot be used.
+

+Subject: [PATCH] ath10k: fix spectral scan for QCA9984 and QCA9888 chipsets
+
+The spectral scan has been always broken on QCA9984 and QCA9888.
+
+Introduce a hardware parameter 'spectral_bin_offset' to resolve this issue for
+QCA9984 and QCA9888 chipsets. For other chipsets, the hardware parameter
+'spectral_bin_offset' is zero so that existing behaviour is retained as it is.
+
+In QCA9984 and QCA9888 chipsets, hardware param value 'spectral_bin_discard'
+is 12 bytes. This 12 bytes is derived as the sum of segment index (4 bytes),
+extra bins before the actual data (4 bytes) and extra bins after the actual
+data (4 bytes). Always discarding (12 bytes) happens at end of the samples and
+incorrect samples got dumped, so that user can find incorrect arrangement
+samples in spectral scan dump.
+
+To fix this issue, we have to discard first 8 bytes and last 4 bytes in every
+samples, so totally 12 bytes are discarded. In every sample we need to consider
+the offset while taking the actual spectral data. For QCA9984, QCA9888 the
+offset is 8 bytes (segment index + extra bins before actual data).
+
+Hardware tested: QCA9984 and QCA9888
+Firmware tested: 10.4-3.5.3-00053

likelly for backward compatiblity with vht80 only capable clients.
this patch adjusts the handling to get vht160 to work again with official qca firmwares newer than 3.3
consider that this patch will not work with older firmwares anymore. to avoid undefined behaviour this we disable vht160 capability for outdated firmwares
