Subject: wcn36xx: Transition driver to SMD client

The wcn36xx wifi driver follows the life cycle of the WLAN_CTRL SMD
channel, as such it should be a SMD client. This patch makes this
transition, now that we have the necessary frameworks available.

Subject: wcn36xx: Implement firmware assisted scan

Using the software based channel scan mechanism from mac80211 keeps us
offline for 10-15 second, we should instead issue a start_scan/end_scan
on each channel reducing this time.

Subject: ath9k: ar9002_mac: kill off ACCESS_ONCE()

For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
preference to ACCESS_ONCE(), and new code is expected to use one of the
former. So far, there's been no reason to change most existing uses of
ACCESS_ONCE(), as these aren't currently harmful.

However, for some new features (e.g. KTSAN / Kernel Thread Sanitizer),
it is necessary to instrument reads and writes separately, which is not
possible with ACCESS_ONCE(). This distinction is critical to correct
operation.

It's possible to transform the bulk of kernel code using the Coccinelle
script below. However, for some files (including the ath9k ar9002 mac
driver), this mangles the formatting. As a preparatory step, this patch
converts the driver to use {READ,WRITE}_ONCE() without said mangling.

Subject: ath10k: refactor ath10k_peer_assoc_h_phymode()

When adding VHT160 support to ath10k_peer_assoc_h_phymode() the VHT mode
selection code becomes too complex. Simplify it by refactoring the vht part to
a separate function.

Subject: ath10k: add VHT160 support

This patch adds full VHT160 support for QCA9984 chipsets Tested on Netgear
R7800. 80+80 is possible, but disabled so far since it seems to contain
glitches like missing vht station flags (this may be firmware or mac80211
related).

Subject: ath10k: add accounting for the extended peer statistics

The 10.4 firmware adds extended peer information to the
firmware's statistics payload. This additional info is
stored as a separate data field and the elements are
stored in their own "peers_extd" list.

These elements can pile up in the same way as the peer
information elements. This is because the
ath10k_wmi_10_4_op_pull_fw_stats() function tries to
pull the same amount (num_peer_stats) for every statistic
data unit.

Subject: ath9k: move RELAY and DEBUG_FS to ATH9K[_HTC]_DEBUGFS

Currently, the common ath9k_common module needs to have a
dependency on RELAY and DEBUG_FS in order to built. This
is usually not a problem. But for RAM and FLASH starved
AR71XX devices, every little bit counts.

This patch adds a new symbol CONFIG_ATH9K_COMMON_DEBUG
which makes it possible to drop the RELAY and DEBUG_FS
dependency there and move it to ATH_(HTC)_DEBUGFS.

Note: The shared FFT/spectral code (which is the only user
of the relayfs in ath9k*) needs DEBUG_FS to export the relayfs
interface to dump the data to userspace. So it makes no sense
to have the functions compiled in, if DEBUG_FS is not there.

Subject: ath10k: fix wifi connectivity and warning in rx with channel 169

In countries where basic operation of channel 169 is allowed,
this fixes the below WARN_ON_ONCE in Rx and fixes the station
connectivity failure in channel 169 as the packet is dropped
in the driver as the current check limits to channel 165. As of
now all the packets beyond channel 165 is dropped, fix this
by extending the range to channel 169.

Subject: ath10k: prevent sta pointer rcu violation

Station pointers are RCU protected so driver must
be extra careful if it tries to store them
internally for later use outside of the RCU
section it obtained it in.

It was possible for station teardown to race with
some htt events. The possible outcome could be a
use-after-free and a crash.

Only peer-flow-control capable firmware was
affected (so hardware-wise qca99x0 and qca4019).

This could be done in sta_state() itself via
explicit synchronize_net() call but there's
already a convenient sta_pre_rcu_remove() op that
can be hooked up to avoid extra rcu stall.

The peer->sta pointer itself can't be set to
NULL/ERR_PTR because it is later used in
sta_state() for extra sanity checks.

Subject: ath10k: fix per station tx bit rate reporting

Not clearing the previous tx bit rate status
results in a ambigous tx bit rate reporting to
mac80211/cfg80211, for example the previous bit
rate status would have been marked as legacy rate
, while the current rate would have been an HT/VHT
rate with the tx bit rate flags set and this results
in exporting tx bitrate as legacy rate but with HT/VHT
rate flags set, fix this by clearing the tx bitrate
status for each event. This also fixes the below
warning when we do:

iw dev wlan#N station dump

Subject: wil6210: add disable_ap_sme module parameter

By default, AP SME is handled by driver/FW.
In case disable_ap_sme is true, driver doesn't turn-on
WIPHY_FLAG_HAVE_AP_SME and the responsibility for
AP SME is passed to user space.

With AP SME disabled, driver reports assoc request frame
to user space which is then responsible for sending assoc
response frame and for sending NL80211_CMD_NEW_STATION.
Driver also reports disassoc frame to user space
which should then send NL80211_CMD_DEL_STATION.

NL80211_CMD_SET_STATION with NL80211_STA_FLAG_AUTHORIZED
is used by user space to allow/disallow data transmit.

Subject: wil6210: support loading dedicated image for sparrow-plus devices

Driver may be used in platforms where some use sparrow cards while
other use sparrow-plus cards, where different FW image is needed.
Add the capability to load dedicated FW image in case sparrow-plus
card is detected and fallback to default image if such does not exist.

Subject: wil6210: remove __func__ from debug printouts

__func__ is automatically added to printouts by dynamic debug
mechanism and by wil_info/wil_err macros.
Remove __func__ from debug printouts to avoid duplication.

Subject: wil6210: support new WMI-only FW capability

WMI_ONLY FW is used for testing in production. It cannot be used for
scan/connect, etc.
In case FW reports this capability, driver will not allow interface up.

Subject: wil6210: missing reinit_completion in wmi_call

The code in wmi_call uses the wil->wmi_call completion
structure to wait for a reply.
In some scenarios, complete was called twice on the
completion structure. This happened mainly with a disconnect
event which can arrive both unsolicited and as a reply to
a disconnect request. In this case the completion structure
was left marked as "done" and the next wmi_call returned
immediately with a corrupted reply buffer. This caused
unexpected results including crashes.
Fix this by adding the missing call to reinit_completion.

Subject: wil6210: protect against false interrupt during reset sequence

During reset sequence it is seen that device is generating an
interrupt eventhough interrupts are masked at device level.

Add workaround to disable the interrupts from host side during
reset and clear any pending interrupts before re-enabling
the interrupt.

Subject: wil6210: fix for broadcast workaround in PBSS

Currently we do not have full support for broadcast from
a station inside a PBSS network.
We have a workaround where instead of broadcast we do a
unicast to every known station in the PBSS.
This workaround was performed only for P2P clients.
This fix will perform the broadcast workaround also for a
regular station inside a PBSS.

The abft_len must be set before starting AP/PCP. It is only

Subject: ath10k: fix typo in addr calculation

CORE_CTRL_ADDRESS is offset in register address space, it does not
make sense to OR it to derive the final address. It looks like its
a typo, so fix it.

Subject: ath10k: Search SMBIOS for OEM board file extension

Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified, among others, by device and sybsystem ids.

The problem, however, can occur when the (default) board data file cannot
fulfill with the vendor requirements and it is necessary to use a different
board data file.

To solve the issue QCA uses SMBIOS type 0xF8 to store Board Data File Name
Extension to specify the extension/variant name. The driver will take the
extension suffix into consideration and will load the right (non-default)
board data file if necessary.

If it is unnecessary to use extension board data file, please leave the
SMBIOS field blank and default configuration will be used.

Example:
If a default board data file for a specific board is identified by a string
      "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028,
       subsystem-device=0310"
then the OEM specific data file, if used, could be identified by variant
suffix:
      "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028,
       subsystem-device=0310,variant=DE_1AB"
