This patch handles the updating of MU-EDCA parameters indicated by
driver. Driver requests to update the parameters and Parameter Set
Update Count in beacon frames. This patch addresses only AP mode.
Three actions are taken to successfully update MU-EDCA parameters
in beacon:
(1) Update MU-EDCA parameters stored in hostapd
The following Access Categories (AC) are updated:
VO: Voice
VI: Video
BE: Best Effort
BK: Background
(2) Increment Parameter Set Update Count
(3) Update beacon with new parameters
There aren't any options to configure, hostapd simply updates MU-EDCA
published by ath11k driver.
To verify params are getting updated, set log_level to '1' and check
logger
i.e. `uci set wireless.radio0.log_level=1`
```

ath11k: fix monitor mode
Enabling CPTCFG_ATH11K_MEM_PROFILE_512M will change the layout of

Revert to using the default kernel timer (CONFIG_HZ_100).
Setting the timer to 1000hz is unecessary and just adds CPU overhead. It
also causes atomic scheduling issues in various threaded tasks,
especially when using threaded NAPI.
When the kernel timer frequency is set to 1000 Hz, it generates interrupts
1000 times per second. This increased frequency can lead to more
frequent context switches and interrupt handling, which can
interfere with other kernel activities.
Since network packet processing is offloaded to the NSS cores, the main CPU
does not need high-resolution timer interrupts to manage network
traffic efficiently. The NSS cores handle this independently.
This is the setting used and recommended by Qualcomm for all their IPQ
platforms.

The following options can now be specified in `pbuf` uci config.
1.) auto_scale (bool) - enable or disable NSS CPU auto-scaling.
default: 'off'.
NOTE: Recommended to leave off, as it locks
NSS core to it's full 1.7Ghz speed. In the past
auto_scaling has been unstable, often causing
kernel panics or connection drops. Qualcomm
themselves disables scaling in QSDK for
ath11k/ath12k/qca-wifi.
It is provided to allow users wanting more
control over power usage. Setting to 'on' also
fixes NSS CPU stats updating properly.
2.) n2h_queue_limit_core0 (int) - set queue limits for CORE 0 and 1.
default: '2048'
For users on low memory systems (<=512M),
that are experiencing issues can try lowering
to the driver default of '256'.
This patch was mostly cosmetic for ipq8074 to supress warnings about
invalid memory region. In this case the M3 dump region. This isn't
necessary for operation or offloading, and is used for firmware
debugging.
However due to the memory layout of ipq6018 it was causing issues of NSS
offloading properly loading. 'idx' shouldn't be incremented, and instead
should just break.

While freeing skb in tx completion path for status reinject, inspect

is using functions from mac80211 to free an skb then it should do
it consistently and not switch to the generic dev_kfree_skb_any.
Otherwise, mac80211 will not be aware of the freed skb and thus
not clean up related information in its internal data structures.

This warning can trigger if there is a mismatch between frames that were
sent with the sta pointer set vs tx status frames reported for the sta address.
This can happen due to race conditions on re-creating stations, or even
in the case of .sta_add/remove being used instead of .sta_state, which can cause
frames to be sent to a station that has not been uploaded yet.
If there is an actual underflow issue, it should show up in the device airtime

In ath11k_dp_rx_msdu_coalesce(), rxcb is fetched from skb and bool
is_continuation is part of rxcb.
Currently, after freeing the skb, the rxcb->is_continuation accessed

Hence fix the issue by locally defining bool is_continuation from rxcb,
so that after freeing skb also we can use is_continuation.

Disable software input output translation lookaside buffer (swiotlb) as
it wastes memory on low memory platforms (512m or less)

Disabling swiotlb is only required for platforms with 512M or less to save
64mb.
The performance of Qualcomm Crypto Engine is 10x slower than kernel
based encryption via ARMv8 crypto extensions. Rather than building it
into the kernel allow users to select it as module which can be tested with
other HW based crypto APIs via cryptodev-linux.
Since SKB recycler was merged into main nss-wifi branch, it is not
necessary to manually tinker with pbuf script. Memory is now properly
managed between NSS driver allocating/deallocating SKBs. For optimal
wifi performance, especially upload, it is advised to leave the script
to 'auto'.
Users who use sysupgrade should manually set the uci config
'/etc/config/pbuf' as it will not overwrite existing configuration.
QSDK NSS builds utilize skbuff recycling for better handling of memory.
On a Dynalink DL-WRX36 (pbuf script should be set to 'auto') a significant drop in
memory usage was observed as well consistent sustained RX/TX speeds.

NOTE:
For 512MB platforms, users need to test with the following scenarios,
as the patch `999-233-ath11k-Disable-rx_header-tlv-for-2K-SKB.patch` is
really only testable on platforms with 512M or less RAM.
1.) Explicitly setting 'ATH11K_MEM_PROFILE_512M' on and see if system
crashes on boot.
2.) Explicitly setting 'ATH11K_MEM_PROFILE_1G'
3.) Remove patches

999-311-ath11k-configure-nss-thread-priority-during-pdev_ini.patch

The peer delete logic in ath11k_mac_op_unassign_vif_chanctx() is
introduced by commit b4a0f54156ac ("ath11k: move peer delete after
vdev stop of station for QCA6390 and WCN6855") to fix firmware
crash issue caused by unexpected vdev stop/peer delete sequence.
Actually for a STA interface peer should be deleted in
ath11k_mac_op_sta_state() when STA's state changes from
IEEE80211_STA_NONE to IEEE80211_STA_NOTEXIST, which also coincides
with current peer creation design that peer is created during
IEEE80211_STA_NOTEXIST -> IEEE80211_STA_NONE transition. So move
peer delete back to ath11k_mac_op_sta_state(), also stop vdev before
deleting peer to fix the firmware crash issue mentioned there. In
this way the connection failure mentioned here is also fixed.
Also do some cleanups in patch "wifi: ath11k: remove invalid peer
create logic", and refactor in patches "wifi: ath11k: rename
ath11k_start_vdev_delay()" and "wifi: ath11k: avoid forward declaration
of ath11k_mac_start_vdev_delay()".
Tested this patch set using QCA6390 and WCN6855 on both STA and SAP
interfaces. Basic connection and ping work well.

ath11k_nss: Fix BCCA counter for EMA
Currently BCCA counter is updated to FW via csa counter offs and
beacon with new countdown is updated for every beacon tx completion event.
For EMA, all EMA beacons are updated in one shot, and counter update for
every tx event will mess up the actual sequence of countdown sent over the air.
Allow FW to update the countdown till 1 and finalize the color
change.
