As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.
This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.
The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the
fly. We should investigate changing this to be a per-frame flag.

In the midst of chanctx patch review channel
switching became broken which I failed to notice
until now.
Function ath10k_mac_vif_chan() reports current
chandef which isn't updated until after
switch_vif_chanctx() is returned from.
Consequently the driver just restarted operation
on channels it was residing already instead of
switching to the new ones.

In practice there's no point in having a copy of
chanctx_conf.
Most of the time the channel pointer (and band
along with it) is accessed and this can't change
after a chanctx is created because switching is
done using explicit chanctx swapping via
switch_vif_chanctx().
The only thing that can change within a
chanctx_conf and is used by the driver is
radar_enabled and channel width. These are however
always accessed in adequate mac80211 callback
context which guarantees safe access to the
chanctx data.

Channel contexts aren't iterable until after
they've been added to the driver. The code assumed
otherwise.
This problem could result in:
* rx_channel being NULL and forcing Rx path to go
the slow way to get channel on QCA988X,
* report incorrect channel when running
multi-channel on QCA61X4 hw2.1,
* report incorrect channel after AP channel
switch.

Some of of qca988x solutions are having global reset issue
during target initialization. Bypassing PLL setting before
downloading firmware and letting the SoC run on REF_CLK is fixing
the problem. Corresponding firmware change is also needed to set
the clock source once the target is initialized. Since 10.2.4
firmware is having this ROM patch, applying skip_clock_init only
for 10.2.4 firmware versions.

In some cases some channel survey data was
reported incorrect.
Channel info events were expected to come in pairs
without and with COMPLETE flag set respectively
for each channel visit during scan.
The known deviation from this is rule for last
scan chan info and first (next) scan chan info
both have COMPLETE flag set. This was either
programmed with the intent of providing BSS cycle
count info or this is an artefact of firmware scan
state machine. Either way this is useless due to
short wraparound time, wraparound quirks and no
overflow notification.
Survey dumps now include only data gathered during
scan channel visits that can be computed
correctly.
This should improve hostapd ACS a little bit.

When QCA988X cycle counter HW register wraps
around it resets to 0x7fffffff instead of 0. All
other cycle counter related registers are divided
by 2 so they never wraparound themselves. QCA61X4
has a uniform CC and it wraparounds in a regular
fashion though.
Worst case wraparound time is approx 24 seconds
(2**31 / 88MHz). Since scan channel visit times
are max 5 seconds (offchannel case) it is
guaranteed there's been at most 1 wraparound and
it is possible to compute survey active time
value. It is, however, impossible to determine the
point at which Rx Clear Count has been divided by
two so it is not reported upon wraparound.
This fixes some occasional incorrect survey data
on QCA988X as some channels (depending on how/when
scan/offchannel requests were requested) would
have approx 24 sec active time which wasn't
actually the case.
This should improve hostapd ACS a little bit.

Some firmware revisions pad 4th hw address in
Native Wifi Rx decap. This is the case with 10.x
and it was assumed that this is true for all
firmware images.
However QCA988X with 999.999.0.636 and QCA61X4
with WLAN.RM.2.0-00088 don't have the padding.
Hence add a feature flag indicating that the
padding isn't present so firmware images can
advertise it appropriately. This way driver will
behave as it was before with old firmware blobs
and doesn't cause any regressions from user
perspective.
Effectively this patch enables QCA988X with
999.999.0.636 and QCA61X4 with WLAN.RM.2.0-00088
to set up client bridging provided user has an
updated firmware blob.

By using SOC_WAKE register it is possible to bring
down power consumption of QCA61X4 from 36mA to
16mA when associated and idle.
Currently the sleep threshold/grace period is at a
very conservative value of 60ms.
Contrary to QCA61X4 the QCA988X firmware doesn't
have Rx/beacon filtering available for client mode
and SWBA events are used for beaconing in AP/IBSS
so the SoC needs to be woken up at least every
~100ms in most cases. This means that QCA988X
is at a disadvantage and the power consumption
won't drop as much as for QCA61X4.
Due to putting irq-safe spinlocks on every MMIO
read/write it is expected this can cause a little
performance regression on some systems. I haven't
done any thorough measurements but some of my
tests don't show any extreme degradation.
The patch removes some explicit pci_wake calls
that were added in 320e14b8db51aa ("ath10k: fix
some pci wake/sleep issues"). This is safe because
all MMIO accesses are now wrapped and the device
is woken up automatically if necessary.

Spectral scan supported by ath10k has capability to monitor and report
through whole bands and channels, but current buffer size is too small
to save reported spectral scan data.
This results in dropping 5G channel reports at all when dual band card
is used, so that users are not able to analyze spectral environments.
Hence increase the buffer size to fix the problem.
A spectral data size is vary based on the number of bins, so the unit
buffer size, 1140, is chose to minimize relay buffer fragmentation.
The total buffer size is also chose in tradeoff with spectral scan
support vs. kernel memory consumption.
Since theoretical maximum buffer size, 9.5MB, can be consumed with
512 bins in dual bands, we target to cover up to 128 bins for all
channels in dual bands and due to the buffer size limitation,
spectral scan with bin number bigger than 128 needs to be run on
single band each.

Until now only a single fixed tx rate or nss was
allowed to be set.
The patch attempts to improve this by allowing
most bitrate masks. The limitation is VHT MCS
rates cannot be expressed separately using
existing firmware interfaces and only the
following VHT MCS ranges are supported: none, 0-7,
0-8, and 0-9.
This keeps the old behaviour when requesting
single tx rate or single nss. The new bitrate mask
logic is only applied to other cases that would
return -EINVAL until now.
Depending on firmware revisions some combinations
may crash firmware so use with care, please.
This depends on "ath10k: don't use reassoc flag".
Without it key cache would effectively be
invalidated upon bitrate change leading to
communication being no longer possible.
These work:
iw wlan0 set bitrates legacy-5 6 12 ht-mcs-5 1 2 3
iw wlan0 set bitrates legacy-5 ht-mcs-5 7 8 9
iw wlan0 set bitrates legacy-5 24 ht-mcs-5 vht-mcs-5 1:0-9
These won't work:
iw wlan0 set bitrates legacy-5 ht-mcs-5 vht-mcs-5 1:0-5
iw wlan0 set bitrates vht-mcs-5 2:7-9
(note the invalid VHT MCS ranges)

Some devices differ slightly and require different
board files. If wrong board data is used they
crash or behave incorrectly.
These devices can be differentiated by looking at
PCI subsystem device id. That is the case for
qca61x4 devices at least.
The board specific filename is constructed as:
board-<bus>-<id>.bin
For PCI in particular it is:
board-pci-<vendor>:<dev>:<subsys_vendor>:<subsys_dev>.bin
These files are looked in device/hw specific
directories. Hence for Killer 1525 (qca6174 hw2.1)
ath10k will request:
/lib/firmware/ath10k/QCA6174/hw2.1/board-pci-168c:003e:1a56:1525.bin
To not break any existing setups (e.g. in case
some devices in the wild already have subsys ids)
if a board specific file isn't found a generic one
is used which is the one which would be used until
now. This guarantees that after upgrading a driver
device will not suddenly stop working due to
now-missing specific board file. If this is the
case a "fallback" string is appended to the info
string when driver boots.
Keep in mind this is distinct from cal-pci-*.bin
files which contain full calibration data and MAC
address. Cal data is aimed at systems where
calibration data is stored out of band, e.g. on
nand flash instead of device EEPROM - an approach
taken by some AP/router vendors.
Board files are more of a template and needs some
bits to be filled in by the OTP program using
device EEPROM contents.
One could argue to map subsystem ids to some board
design codename strings instead of using raw ids
when building the board filename. Using a mapping
however would make it a lot more cumbersome and
time consuming (due to how patches propagate over
various kernel trees) to add support for some new
device board designs. Adding a board file is a lot
quicker and doesn't require recompilation.

WLAN survey data provides several informative values on each channels
such as noise, active time, transmit time, and etc.
Regarding the channel activity time data, it is reported from firmware
in different form which is number of cycles instead of time itself.
Hence host driver converts it to time unit by dividing it by clock rate
that is used at baseband MAC.
Using difference clock rate from that actual HW is using will result in
inaccurate survey data. For instance, channel active time can be reported
with bigger than 150ms even though we set Dwell time to 150ms.
Therefore set the clock rate to 88000 (88 MHz) which is ath10k baseband
MAC is using.

With latest additions to the driver it seems
viable to enable support for IBSS-RSN.
It seems to work on QCA988X and 999.999.0.636 but
is a bit slow to exchange RSN keys for some
reason. This may be a firmware quirk or ath10k is
missing something. Nevertheless it makes sense to
finally enable IBSS-RSN in ath10k even if somewhat
handicapped.
QCA6174 firmware doesn't seem to be able to Tx
EAPOL frames at all now (they get stuck in hw
queues for some reason) so it never gets to set
the keys in driver. It's fairly safe to assume that
once this is fixed IBSS-RSN will work with QCA6174
firmware without any additional changes. Hence no
special handling for advertising
IEEE80211_HW_SUPPORTS_PER_STA_GTK and
WIPHY_FLAG_IBSS_RSN is done now.

Apparently firmware requires both pairwise and
groupwise keys to be installed per-peer for static
WEP in IBSS. This wasn't necessary for AP mode
(and installing both doesn't seem to break AP
mode thus there's no special handling).
Also there seems to be some kind of issue with
mapping tx/rx keys in firmware properly which
resulted in wrong keys being used and broken
communication between devices.
It can be argued the vdev param part is more of a
workaround than a real fix. However I couldn't

Until now these keys were installed once as

underneath. From Eric Dumazet.
13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk.
14) Support stable privacy address generation for RFC7217 in IPV6. From
Hannes Frederic Sowa.
15) Hash network namespace into IP frag IDs, also from Hannes Frederic
Sowa.
16) Convert PTP get/set methods to use 64-bit time, from Richard
Cochran.

This improves chances of getting onto a foreign
channel and thus makes P2P a bit more reliable.
Without scan burst it was possible for firmware to
not switch to foreign channel resulting in "failed
to switch to channel for roc scan" warning. This
would also effectively fail some offchan tx
requests and lead to P2P find/connect taking
longer. This could be observed when other vifs
were running/busy, e.g. with P2P GO.

It is not guaranteed firmware will switch to
foreign channel immediately after starting scan
sequence. To account for that don't use duration
parameter for scan time. Instead request insanely
long scan and use timeout worker to cancel it from
driver.
This should improve P2P reliability a bit.

Use the new IEEE80211_TX_STAT_NOACK_TRANSMITTED flag
to indicate successful transmission of no-ack frames.
This fixes multicast frame accounting.

This fix the regerssion introduced after "ath10k_wmi_requests_stats()
call to use more stat bits", both the 10.2.X FW and community FW 10.1.X
will return time out when access the fw_stats with the STAT_VDEV and
STAT_PDEV. Add the condition to use different fw_stats mask for different
FW versions.

The default keyidx callback may be called after
more than 1 key is installed. This led to only 1
WEP key being reinstalled only. This caused Rxed
traffic encrypted with other WEP keys to be
dropped in client mode.

The variable should be cleared regardless of
whether there's a peer associated with the key or
not.
This fixes case when user first associates with 2
WEP keys and then disconnects and connects with 1
WEP key. This resulted in WEP key count being 2 in
the driver leading to default keyidx fixup
failure.

There's always at most 2 credits and it makes
little sense to set the
ATH10K_HTC_FLAG_NEED_CREDIT_UPDATE flag
conditionally.
This seems to fix some random issues with tx
credit starvation on WLAN.RM.2.0-00073 I've been
seeing. Note: this isn't related to wmi mgmt tx.
