This patch fixes a regression introduced in kernel v4.14. While the
commit message only mentions a performance penalty, the issue is
suspected to be the cause of spurious data bus errors on MIPS CPUs
(ar71xx target).
Fixes: #1982
Before, only frames with a maximum size of 1528 bytes could be
transmitted between two 802.11s nodes.
For batman-adv for instance, which adds its own header to each frame,
we typically need an MTU of at least 1532 bytes to be able to transmit
without fragmentation.
This patch now increases the maxmimum frame size from 1528 to 1656
bytes.
Tested with two ath10k devices in 802.11s mode, as well as with
batman-adv on top of 802.11s with forwarding disabled.
Fix originally found and developed by Ben Greear.

As of OpenWrt commit b3d8b3ab8e6f ("mac80211: set noscan=1 if sta/adhoc/
mesh interfaces are present"), the issue workarounded by this patch cannot
occur anymore.
The factory firmware omits the JFFS2 end-marker while flashing via
web-interface. Add a 64k padding after the marker fixes this problem.
When the end-marker is not present, OpenWRT won't save the overlayfs
after initial flash.
If no mcast_rate is set for the wifi-iface then there is no rate_idx (0)
set for the bss. This breaks 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.
Fixes: a399b60735 ("ath10k/ath10k-ct: support multicast and management rate control")
Drivers with software rate control can directly use the selected multicast
rate for multicast/broadcast frames and the minimal basic rate for
management frames. But drivers with offloaded rate control algorithms must
be informed about such upper layer decisions to configure the
hardware/firmware.
A new BSS_CHANGED_MCAST_RATE is introduced in mac80211 to automatically
inform all drivers. ath10k can detect this event and forward it via WMI to
the driver. The already existing BSS_CHANGED_BASIC_RATES can be used to
select the management rate.
Without the WMI commands, a low rate (not necessarily one from the basic
rates) is used for bcast/mcast/management frames. This means that the
/etc/config/wireless settings basic_rate and mcast_rate would have no
effect on the rates selected by this driver for the mentioned frames.
This backports the TP-Link Archer C50 v4.
We are dropping the following upstream commits. They add support for the
TP-Link recovery-flag which enabled the web-recovery. As they are not
needed for the router to work, we drop them for now.

ath10k-ct uses a rather high number of buffers to communicate with the
QCA/Candelatech firmware. Especially the HTC (host-target-communication)
and HTT (host-target-transport) can take up a lot of memory when data is
transferred over a ath10k wifi link.
Even a 256MB device with three radios can go OOM (while sending to three
devices using UDP unicast/multicast packets) with the default buffer
limits. Unfortunately, this also reduced the maximum 5GHz throughput on an
IPQ40xx device from 494/432 Mbit/s for TCP transfers (download/upload) to
438/343 Mbit/s. These throughput values should still be good enough for a
Freifunk installation. And these changes are already used by ath10k in
OpenWrt 18.06.

ath10k has to switch the regulatory domain when switching the default
country when ATH_USER_REGD is enabled. This is for example important when
switching from country US (FCC) to DE (ETSI). The ath implementation will
use ath_reg_dyn_country_user_allow to check if this is allowed.
Unfortunately, this function always seems to return false to
ath_reg_notifier_apply even when ATH_USER_REGD is enabled. But it must
actually always accept the requests from the user (when ATH_USER_REGD is
enabled) to correctly set the conformance test limits in the ath10k binary
blob.
Not doing it will sometimes allow too high transmit powers on edge channels
for correctly calibrated devices outside their default regulatory domain.
