According to many bugreports [0][1][2] the default ath10k-ct kernel
module is unusable on devices with just 64 MiB RAM or with 128 MiB and
dual ath10k cards. The target boards boot but eventually oom-killer
starts to interfere with normal operation, so the current state is
effectively broken.
Since the two patches in question have a performance impact (and
possibly some other unexpected side-effects) a dedicated build variant
is added so that users of the low RAM devices can still benefit from all
the ath10k-ct advantages.
According to testing [3] results, the issue can be experienced even with
"a 256MB device with three radios". Measured performance impact of
implementing small buffers was lowering "the maximum 5 GHz throughput on
an IPQ40xx device without RPS/XPS optimizations from 494/432 Mbit/s for
TCP transfers (download/upload) to 438/343 Mbit/s"
The patches were apparently inspired by QSDK tweaks used by ODMs for the
affected devices.

the ath10k-ct package ships multiple versions of the ath10k-ct driver,
OpenWrt currently only uses the version 4.19, but we still ship some
patches for older versions. Remove all patches only touching older
versions and also remove the patch for older versions from patches which
do the same changes to multiple versions of ath10k-ct.
This removes some unneeded patches, the end binary should stay the same.

This backports upstream commit
34d5629 ath10k: limit available channels via DT ieee80211-freq-limit

are still listed as a supported configuration for the radio.
The identical patch was also backported by OpenWRT to the non-ct driver.
It can be dropped as soon as we switch to an ath10k-ct version based on
4.20 or higher.

If no mcast_rate is set for the wifi-iface then there is no rate_idx (0)
set for the bss. This can break for example 5GHz meshpoint interfaces
because 0 maps to a CCK rate (11Mbit/s).
It must also be avoided that the ath10k-ct internal state for the rates is
not synced with the mac80211 rates state. Otherwise, the user specified
rate (e.g. a wifi-iface mcast_rate for a meshpoint interface) will only be
set on startup. And a short while after that, ath10k-ct specific code in
ath10k_check_apply_special_rates is missing a valid rate in its own
structures and is then recalculating a new default rate. This default rate
is in most situations not the requested rate.

By default the firmware uses 1Mbps and 6Mbps rate for management packets
in 2G and 5G bands respectively. But when the user selects different
basic rates from the userspace, we need to send the management
packets at the lowest basic rate selected by the user.
This change makes use of WMI_VDEV_PARAM_MGMT_RATE param for configuring the
management packets rate to the firmware.

Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified on QCA4019 using bus, bmi-chip-id and
bmi-board-id.
The problem, however, can occur when the (default) board data file cannot
fulfill the vendor requirements and it is necessary to use a different
board data file.
This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8.
Something similar has to be provided for systems without SMBIOS but with
device trees. No solution was specified by QCA and therefore a new one has
to be found for ath10k.
The device tree requires addition strings to define the variant name
wifi@a000000 {
status = "okay";
qcom,ath10k-calibration-variant = "RT-AC58U";
};
wifi@a800000 {
status = "okay";
qcom,ath10k-calibration-variant = "RT-AC58U";
};
This would create the boarddata identifiers for the board-2.bin search
* bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U
* bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U

Backport patches that separate spectral scan support from general debugfs
support of ath9k/ath10k; this allows to remove the dependency on
KERNEL_RELAY from these driver packages even with debugfs enabled and
avoids the memory footprint of the relay buffers allocated by ath9k/ath10k
even when they aren't used at all.
The KERNEL_RELAY dependency is moved to a new config symbol that enables
spectral scan support in these drivers.

This updates mac80211 to backprots-4.14-rc2.
This was compile and runtime tested with ath9k, ath10k and b43
with multiple stations and ieee80211w and in different scenarios by many
other people.
To create the backports-4.14-rc2-1.tar.xz use this repository:
https://git.kernel.org/pub/scm/linux/kernel/git/backports/backports.git
from tag v4.14-rc2-1
Then run this:
./gentree.py --git-revision v4.14-rc2 --clean <path to linux repo> ../backports-4.14-rc2-1
This also adapts the ath10k-ct and mt76 driver to the changed cfg80211
APIs and syncs the nl80211.h file in iw with the new version from
backports-4.14-rc2.
