Fix typos and add the following to the scripts/spelling.txt:
aligment||alignment
I did not touch the "N_BYTE_ALIGMENT" macro in
drivers/net/wireless/realtek/rtlwifi/wifi.h to avoid unpredictable
impact.
I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because
it is surrounded by #if 0 ... #endif. It is surely safe and I
confirmed "_alignment_handler" is correct.
I also fixed the "controler" I found in the same hunk in
arch/openrisc/kernel/head.S.

This reverts commit f2593cb1b2.
Paul reported that this patch with older board-2.bin ath10k initialisation
fails on Dell XPS 13:
ath10k_pci 0000:3a:00.0: failed to fetch board data for bus=pci,vendor=168c,
device=003e,subsystem-vendor=1a56,subsystem-device=1535,variant=RV_0520 from
ath10k/QCA6174/hw3.0/board-2.bin
The reason is that the older board-2.bin does not have the variant version of
the image name and ath10k does not fallback to the older naming scheme.

This patch fixes the OTP register definitions for the AR934x and AR9550
WMAC SoC.
Previously, the ath9k driver was unable to initialize the integrated
WMAC on an Aerohive AP121:
| ath: phy0: timeout (1000 us) on reg 0x30018: 0xbadc0ffe & 0x00000007 != 0x00000004
| ath: phy0: timeout (1000 us) on reg 0x30018: 0xbadc0ffe & 0x00000007 != 0x00000004
| ath: phy0: Unable to initialize hardware; initialization status: -5
| ath9k ar934x_wmac: failed to initialize device
| ath9k: probe of ar934x_wmac failed with error -5
It turns out that the AR9300_OTP_STATUS and AR9300_OTP_DATA
definitions contain a typo.

ath_tx_count_airtime is doing a lot of unnecessary work:
- Redundant station lookup
- Redundant rcu_read_lock/unlock
- Useless memcpy of bf->rates
- Useless NULL check of bf->bf_mpdu
- Redundant lookup of the skb tid
Additionally, it tries to look up the mac80211 queue index from the txq,
which fails if the frame was delivered via the power save queue.
This patch fixes all of these issues by passing down the right set of
pointers instead of doing extra work

Firmware files are versioned to prevent older
driver instances to load unsupported firmware
blobs. This is reflected with a fallback logic
which attempts to load several firmware files.
This however produced a lot of unnecessary
warnings sometimes confusing users and leading
them to rename firmware files making things even
more confusing.
Hence use request_firmware_direct() which does not
produce extra warnings. This shouldn't really
break anything because most modern systems don't
rely on udev/hotplug helpers to load firmware
files anymore. For example it was confirmed that
LEDE does not user helper.
This also fixes a 60 second delay per _each_
unexistent firmware/calibration file with distros
which have CONFIG_FW_LOADER_USER_HELPER_FALLBACK
enabled, RHEL being a notable example. Using
ath10k with firmware-2.bin this might end up
into a five minute delay in boot.

This fixes the below crash when ath10k probe firmware fails, NAPI polling tries
to access a rx ring resource which was never allocated. An easy way to
reproduce this is easy to remove all the firmware files, load ath10k modules
and ath10k will crash when calling 'rmmod ath10k_pci'. The fix is to call
napi_enable() from ath10k_pci_hif_start() so that it matches with
napi_disable() being called from ath10k_pci_hif_stop().
Big thanks to Mohammed Shafi Shajakhan who debugged this and provided first
version of the fix. In this patch I just fix the actual problem in pci.c
instead of having a workaround in core.c.

The code currently relies on refcounting to disable IRQs from within the
IRQ handler and re-enabling them again after the tasklet has run.
However, due to race conditions sometimes the IRQ handler might be
called twice, or the tasklet may not run at all (if interrupted in the
middle of a reset).
This can cause nasty imbalances in the irq-disable refcount which will
get the driver permanently stuck until the entire radio has been stopped
and started again (ath_reset will not recover from this).
Instead of using this fragile logic, change the code to ensure that
running the irq handler during tasklet processing is safe, and leave the
refcount untouched.

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"

Add an option to specify and override the A-BFT length when
starting an AP/PCP. See IEEE P802.11-2016, 10.38.5.
The abft_len must be set before starting AP/PCP. It is only
needed for diagnostics and certification.

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.

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.

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.

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.

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:

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.
