Subject: [PATCH] ath9k: dynack: use authentication messages for 'late' ack
In order to properly support dynack in ad-hoc mode running
wpa_supplicant, take into account authentication frames for
'late ack' detection. This patch has been tested on devices
mounted on offshore high-voltage stations connected through
~24Km link

Subject: [PATCH] brcmfmac: reduce timeout for action frame scan
Finding a common channel to send an action frame out is required for
some action types. Since a loop with several scan retry is used to find
the channel, a short wait time could be considered for each attempt.
This patch reduces the wait time from 1500 to 450 msec for each action
frame scan.
This patch fixes the WFA p2p certification 5.1.20 failure caused by the
long action frame send time.

Subject: [PATCH] brcmfmac: fix full timeout waiting for action frame
on-channel tx
The driver sends an action frame down and waits for a completion signal
triggered by the received BRCMF_E_ACTION_FRAME_OFF_CHAN_COMPLETE event
to continue the process. However, the action frame could be transmitted
either on the current channel or on an off channel. For the on-channel
case, only BRCMF_E_ACTION_FRAME_COMPLETE event will be received when
the frame is transmitted, which make the driver always wait a full
timeout duration. This patch has the completion signal be triggered by
receiving the BRCMF_E_ACTION_FRAME_COMPLETE event for the on-channel
case.
This change fixes WFA p2p certification 5.1.19 failure.

Subject: [PATCH] brcmutil: really fix decoding channel info for 160 MHz
bandwidth
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Previous commit /adding/ support for 160 MHz chanspecs was incomplete.
It didn't set bandwidth info and didn't extract control channel info. As
the result it was also using uninitialized "sb" var.
This change has been tested for two chanspecs found to be reported by
some devices/firmwares:
1) 60/160 (0xee32)
Before: chnum:50 control_ch_num:36
After: chnum:50 control_ch_num:60
2) 120/160 (0xed72)
Before: chnum:114 control_ch_num:100
After: chnum:114 control_ch_num:120
Fixes: 330994e8e8ec ("brcmfmac: fix for proper support of 160MHz bandwidth")

Subject: [PATCH] brcmfmac: Remove recursion from firmware load error handling
Before this commit brcmf_fw_request_done would call
brcmf_fw_request_next_item to load the next item, which on an error would
call brcmf_fw_request_done, which if the error is recoverable (*) will
then continue calling brcmf_fw_request_next_item for the next item again
which on an error will call brcmf_fw_request_done again...
This does not blow up because we only have a limited number of items so
we never recurse too deep. But the recursion is still quite ugly and
frankly is giving me a headache, so lets fix this.
This commit fixes this by removing brcmf_fw_request_next_item and by
making brcmf_fw_get_firmwares and brcmf_fw_request_done directly call
firmware_request_nowait resp. firmware_request themselves.
*) brcmf_fw_request_nvram_done fallback path succeeds or
BRCMF_FW_REQF_OPTIONAL is set

Subject: [PATCH] brcmfmac: Add support for first trying to get a board
specific nvram file
The nvram files which some brcmfmac chips need are board-specific. To be
able to distribute these as part of linux-firmware, so that devices with
such a wifi chip will work OOTB, multiple (one per board) versions must
co-exist under /lib/firmware.
This commit adds support for callers of the brcmfmac/firmware.c code to
pass in a board_type parameter through the request structure.
If that parameter is set then the code will first try to load
chipmodel.board_type.txt before falling back to the old chipmodel.txt name.

For of/devicetree using machines, set the board_type used for nvram file
selection to the first string listed in the top-level's node compatible
string, aka the machine-compatible as used by of_machine_is_compatible().
The board_type setting is used to load the board-specific nvram file with
a board-specific name so that we can ship files for each supported board
in linux-firmware.

Subject: [PATCH] brcmfmac: Set board_type from DMI on x86 based machines
For x86 based machines, set the board_type used for nvram file selection
based on the DMI sys-vendor and product-name strings.
Since on some models these strings are too generic, this commit also adds
a quirk table overriding the strings for models listed in that table.
The board_type setting is used to load the board-specific nvram file with
a board-specific name so that we can ship files for each supported board
in linux-firmware.

Subject: [PATCH] brcmfmac: Cleanup brcmf_fw_request_done()
The "cur" variable is now only used for a debug print and we already
print the same info from brcmf_fw_complete_request(), so the debug print
does not provide any extra info and we can remove it.

Subject: [PATCH] brcmfmac: Add support for getting nvram contents from EFI
variables
Various X86 laptops with a SDIO attached brcmfmac wifi chip, store the
nvram contents in a special EFI variable. This commit adds support for
getting nvram directly from this EFI variable, without the user needing
to manually copy it.
This makes Wifi / Bluetooth work out of the box on these devices instead of
requiring manual setup.
This has been tested on the following models: Acer Iconia Tab8 w1-810,
Acer One 10, Asus T100CHI, Asus T100HA, Asus T100TA, Asus T200TA and a
Lenovo Mixx 2 8.

Subject: [PATCH] brcmfmac: Fix ccode from EFI nvram when necessary
In some cases the EFI-var stored nvram contains "ccode=ALL" or "ccode=XV"
to specify "worldwide" compatible settings, but these 2 ccode-s do not work
properly.
I've tested the different known "worldwide" ccode-s used in various nvram
sources with the latest firmwares from linux-firmware for various brcmfmac
models, here is a simplified (*) table with what each setting results in:
ALL: 12-14 disab, U-NII-1, U-NII-2 no-IR/radar, U-NII-3
XV: 12-14 no-IR, disables all 5G channels
XY: 12-13 enab, 14 disab, U-NII-1 enab, U-NII-2 no-IR/radar, U-NII-3 disab
X2: 12-13 no-IR, 14 dis, U-NII-1 no-IR, U-NII-2 no-IR/radar, U-NII-3 no-IR
Where 12,13,14 are 2.4G channels 12-14 and U-NII-1/2/3 are the 3 different
5G channel groups. no-IR is no-Initiate-Radiation, we will never send on
these channels without first having received valid wifi traffic there.
This immediately shows that both ALL and XV are not as worldwide as we want
them to be. ALL causes channels 12 and 13 to not be available and XV causes
all 5GHz channels to not be available. Also ALL unconditionally enables the
U-NII-1 and U-NII-3 5G groups, while we really should be using no-IR for
these.
This commit replace XV and ALL with X2, which allows usage of chan 12-13
and 5G channels, but only after receiving valid wifi traffic there first.
Note that this configure the firmware's channel limits, the kernels own
regulatory restrictions based on e.g. regulatory info received from the
access-point, will be applied on top of this.
This fixes channels 12+13 not working on the Asus T200TA and the Lenovo
Mixx 2 8 and 5G channels not working on the Asus T100HA.
This has been tested on the following models: Acer Iconia Tab8 w1-810,
Acer One 10, Asus T100CHI, Asus T100HA, Asus T100TA, Asus T200TA and a
Lenovo Mixx 2 8.
*) There are some exceptions to this table:
1) On really old firmware e.g. linux-firmware's 2011 brcmfmac4330-sdio.bin
ALL really means all, unconditionally enabling everything
2) The exact meaning might be influenced by setting the regrev nvram var.
Specifically using ccode=XV + regrev=1 on brcmfmac43241b4 leads to:
12-14 no-ir, U-NII-1 no-ir, U-NII-2 no-ir/radar, U-NII-3 no-ir
But only on the brcmfmac43241b4 and not on e.g. the brcmfmac43340

From: Felix Fietkau <nbd@nbd.name>
Date: Tue, 13 Nov 2018 20:29:03 +0100
Subject: [PATCH] mac80211: ignore tx status for PS stations in
ieee80211_tx_status_ext
Make it behave like regular ieee80211_tx_status calls, except for the lack of
filtered frame processing.
This fixes spurious low-ack triggered disconnections with powersave clients
connected to an AP.
Fixes: f027c2aca0cf4 ("mac80211: add ieee80211_tx_status_noskb")
