Attempt at getting NSS WiFi Offload working on kernel 6.1 (backport 6.5)

These patches are a mix of @Ansuel branch for 5.15 (ipq807x-5.15-ecm-wifi)
Ansuel@3ecaee7

And QUIC's upstream NSS patches on [NHSS.QSDK.12.4.5.r3](https://git.codelinaro.org/clo/qsdk/oss/system/feeds/wlan-open.git)
For the actual package setup (Makfiles,ath.mk) Qualcomm's branch is under 'wlan-open/NHSS.QSDK.12.4.5.r3'

Looks like they've swtiched to using backports 6.5-rc3, and figured to
use a mix of their patches on 'NHSS.QSDK.12.4.5.r3' (nss)
'wlan-open/NHSS.QSDK.12.4.5.r3' (syncing with openwrt main).

Booting with "nss_offload=1 frame_mode=2"

ath11k-nss: Wifi offloading working (unstable)

Wifi offloading seems to be working, however it is not stable. Logs will
initially show a lot of flooding.

```

But eventually ends up subsiding. Needs heavy testing...

ath11k_nss: Add mac address to debug `nss peer delete` warnings

also delete ath10k patch, and refresh.

ath11k_nss: FIX `nss peer delete` + encap errors

This should hopefullly fix the following errors:

```

[Sun Dec 24 22:08:25 2023] ath11k c000000.wifi: failed to transmit frame -22
```

Clients should also be able to switch between 2Ghz and 5Ghz AP, as well
as join using password (no longer required to boot with NSS off first,
connect the client to acquire PSK, and reboot back with nss wifi offload
enabled).

Uptime has been 5 hours and so far no issues.

ath11k_nss: Remove unecessary clang-tidy formatting

ath11k_nss: add 'debug_mode' flag quiet warnings

Will properly handle:
```
[Mon Dec 25 16:51:34 2023] ath11k c000000.wifi: encap mismatch in nss tx skb encap type 1 vif encap type 2
```

should take the path for native wifi encap

ath11k_nss: Rework depends, make `nss_redirect` optional

1.) Added a reworked `qca-nss-pbuf` init script from QSDK that will set sysctl
    NSS `n2hcfg` wifi options based on board type and available
    RAM.

2.) ath11k is fully capable of offloading wifi, it does not need
    mac80211 to create any NSS vifs. This lowers overhead and has actually
    shown considerable speed improvements for CPU programs on the router
    side (i.e. SMB). I believe ax3600's IoT (ath10k) would require it
    for offloading.

    I've added 2 new makemenu options, `MAC80211_NSS_SUPPORT` which enables
    NSS related features, and `MAC80211_NSS_REDIRECT` which provides the option to
    autoload the module on boot with `nss_redirect=1`.

3.) Reverted the option that deafulted `ATH11K_MEM_PROFILE_512M` to
    true. This was not required for platforms with 1GB or more memory
    (which is most of them). The default is 1GB. Select for platforms
    like Xiaomi AX3600.

ath11k_nss: remove requirement for '/sys/kernel/debug/ath11k'

ath11k_nss: set default values lower to avoid eating up memory

ath11k_nss: Add NSS VLAN support + improvements

1) tweaked qca-nss-pbuf script to better handle different board configs
2) added some QSDK NSS patches for dynamic vlan, WDS.
3) added QSDK fixes for beacon, and bt-coex

For devices that keep getting disconnected (mostly on 2G). It is
recommended to use the following settings for wifi. Change for your
country.

config wifi-device 'radio0'
	option type 'mac80211'
	option path 'platform/soc/c000000.wifi'
	option band '5g'
	option txpower '24'
	option country 'PA'
	option channel '100'
	option htmode 'HE160'
	option cell_density '0'

config wifi-iface 'default_radio0'
	option device 'radio0'
	option network 'lan'
	option mode 'ap'
	option encryption 'psk2'
	option key 'SOME_PASSWORD'
	option ssid 'EXAMPLE_5G'
	option dtim_period '3'
	option max_inactivity '86400'
	option disassoc_low_ack '0'

config wifi-device 'radio1'
	option type 'mac80211'
	option path 'platform/soc/c000000.wifi+1'
	option band '2g'
	option htmode 'HT20'
	option channel '1'
	option txpower '36'
	option country 'PA'
	option cell_density '0'

config wifi-iface 'default_radio1'
	option device 'radio1'
	option network 'lan'
	option mode 'ap'
	option ssid 'EXAMPLE_2G'
	option encryption 'psk2'
	option key 'SOME_PASSWORD'
	option max_inactivity '86400'
	option dtim_period '3'
	option disassoc_low_ack '0'

WPA3 should be disabled, and left as WPA2. Experimenting with max_inactivity, dtim_period, and disassoc_low_ack to hopefully resolve the deauth disconnects.

`dev.nss.n2hcfg.n2h_wifi_pool_buf` must be set BEFORE setting
`dev.nss.n2hcfg.n2h_high_water_core0`, otherwise it resets the value.

ath11k_nss: bugfix change start order

value 'dev.nss.n2hcfg.n2h_wifi_pool_buf' was not getting set, wait till
after qca-nss-drv is loaded.

ath11k_nss: finally fix n2hcfg values not being set

  Memory allocations in the driver & mac80211 are logged
  and populate those values to the user space via debugfs.
  This stats will give the snapshot of the memory being
  used by the driver at the time of dumping these
  memory stats.

  Command:
  cat /sys/kernel/debug/ath11k/ipq8074\ hw2.0/memory_stats

  Sample output of the stats
  MEMORY STATS IN BYTES:
  malloc size : 6287583
  ce_ring_alloc size: 109308
  dma_alloc size:: 10831860
  htc_skb_alloc size: 3840
  wmi alloc size: 0
  per peer object: 4644
  rx_post_buf size: 5091840
  Total size: 22329075

  User can disable/enable the memory stats accounting with
  the below command.

  echo N > /sys/kernel/debug/ath11k/ipq8074\ hw2.0/enable_memory_stats
  where N = 0 to disable logging, 1 to enable the logging.

  Note: This should be enabled/disabled only after wifi is down.
  User shouldn't enable/disable when the wifi is up to avoid
  accounting the negative values which cause incorrect values
  in the memory stats.

  Command:

  cat /sys/kernel/debug/ieee80211/phyX/memory_stats
  memory stats: malloc_size: 108

In case you want to specify the memory profile to use rather than
letting it autodetect. The following new uci option is introduced.
pbuf.

config general opt
  option memory_profile ''

choices are 1gb, 512mb, 256mb. Delete option to let it autodetect.

NOTE: You must reboot after changing these settings, for it to
autoapply.

ath11k_nss: fix compilation and rename some patches

also support offload for the following:

  mac80211:
    * vlan
    * mesh (partial)
  ath11k:
    * vlan

bugfixes:
  * Rreverted patch `105-ath11k-fix-monitor-crash-if-tx-offload-is-enabled.patch`.
    Initial test show lower memory use. `ieee80211_tx_status_8023` was
    also removed upstream for a reason as it wasn't being used, and the
    logic behind it was flawed.
    See https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]

  * Mmemory profile for '256M' was missing logic that was in 512/1G.
    Should build correctly now

  * added more qsdk related patches to nss/offload

ath11k_nss: fix up patches

ath11k_nss: revert m3, fix coredump when rebooting

patches into a subset of nss for better tracking against QSDK,
and modularization.

* Added menuconfig option "ATH11K_NSS_MESH_SUPPORT" to selectivley build mesh support,
	as well it's depenacndy on nss-drv-wifimeshmgr.
* Added option to disable HTT Stats, and STA stats (stations).
* Reducing footprint by ~210KB. Debugfs minimal is still enabled.
* Reworked a TON of patches, some my own, hopefully there should be a far less amount of WOA2/WPA3 connection issues.
* Updated the /etc/init.d/pbuf script to be more robust. (handles tweaking ath11k and NSS settings better)

NOTES: Although mesh package builds (nss-drv-wifimeshmgr), ath11k doesn't seem to support it yet.
Not sure if NSS requires 3 radios to work, I'm at a dead end currently with that route.

ATTENTION:
the ptch `37-006-ath11k-Allow-fast-rx-by-bypassing-stats-update.patch`
works well on nss with frame_mode=2.
And on `ath11k frame_mode=1 nss_offload=0`

And on `ath11k frame_mode=2 nss_offload=1`

if you set nss_offload=off and frame_mode=2, it will CRASH
if you set nss_offload=on and frame_mode=2, it will  RUN
if you set nss_offload=off and frame_mode=1, it will RUN

    wifi: mac80211: Add mac hw flag to avoid tx queue in mac80211

    Queue SKB in mac80211 become mandatory from latest 6.1 kernel. Because of
    this queuing, there will be performance degradation. Add hw flag option
    to enable tx queue in Driver/Hardware.

    Driver/hardware can register for HAS_TX_QUEUE HW flag and avoid tx queuing
    in mac80211.

    Add same HW flag checks to avoid accessing skb queues which will be
    NULL or invalid and also NULL checks for sta txqs for NULL or invalid
    access.

ath11k_nss: ath-next fix connection failure due to unexpected peer delete

Currently ath11k_mac_op_unassign_vif_chanctx() deletes peer but
ath11k_mac_op_assign_vif_chanctx() doesn't create it. This results in
connection failure if MAC80211 calls drv_unassign_vif_chanctx() and
drv_assign_vif_chanctx() during AUTH and ASSOC, see below log:

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.

… detection

Implementing the updating of firmware initiated dynamic MU-EDCA
parameters in Beacon IE. Firmware routinely checks its clients and
updates its MU-EDCA values every 3 seconds. Firmware is tuning
MU-EDCA parameters to improve performance. As part of this process,
the firmware informs host about new MU-EDCA values utilizing
WMI_MUEDCA_PARAMS_CONFIG_EVENTID. FW expectation is that host will
update MU-EDCA parameters in the Beacon IE.

not needed for NSS offload and helps save some memory

Leave it set to '0', as it will kernel panic with 2K skb patch. This
flag was incorrectly assumed to save memory on 1G platforms.

ath11k_nss: remove leftover max_tx_ring

it was not removed when applying patch to replace it with 'max_tx_ring =
DP_TCL_NUM_RING_MAX +1'

ath11k_nss: Import bugfix patches

ath11k_nss: Experimental build for IPQ6018

This will require setting the correct `ATH11K_MEM_PROFILE_XXX` for your
platform. Setting it to value lower/higher than physically available
will cause NULL virtual address kernel panics.

I believe this setting was not originally meant to reduce memory
footprint of 1G+ platforms, but to account for platforms that were
512M or less.

Will require tweaking to allow for the old behvaior on 1G+ IPQ807x,
while still saving memory for platforms <= 512M.

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.

Swap:              0           0           0

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
    999-233-ath11k-Disable-rx_header-tlv-for-2K-SKB.patch
    999-311-ath11k-configure-nss-thread-priority-during-pdev_ini.patch

    And re-test with #1 and #2

It was incorrectly assumed that setting a 512M for 1G platforms would save
memory, instead it needs to be explicitly set to know proper memory
regions, otherwise it would cause fw crash.

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.

ath11k_nss: Fix compile for TRACE feature

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.

This will now be the default NSS branch, and will cover
both kernel 6.1 and 6.6 related changes going forward.

qualcommax: NSS: fix up 'nss_region'

Symbols for crypto, ktls, netfilter are removed from from being compiled
into the kernel and instead left up to the user to compile as modules,
as is the case upstream. Other unused qca features were also removed as
they don't apply to ipq807x/6018 and are not upstream.

Common symbols between 6.1/6.6 that are required for NSS related
features have been consolidated into 'config-default'.

There is an average 300kb of savings in the final kernel image as well
decreased compile time.

qualcommax: NSS: consolidate patches and align with 6.1

Update nss-cfi to kernel 6.6

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

qualcommax: only disable swiotlb for platforms <= 512M

Disabling swiotlb is only required for platforms with 512M or less to save
64mb.

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
again which is wrong since the memory is already freed.

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