Split the kmod-video-dma into kmod-video-dma-sg and kmod-video-dma-contig. The old one contained two kmods, but sometimes only one of them is build which caused problems. The configuration options are not manually selectable in the kernel and hidden in OpenWrt. Currently this causes build failures on some targets.

Add support for D-Link DIR-2055 A1 based on similarities to DIR-1960 A1,
as well as various DIR-8xx A1 models. Existing DIR-1960 A1 openwrt
"factory" firmware installs without modifications via the D-Link Recovery
GUI and has no known incompatibilities with the DIR-2055 A1.

new file: target/linux/ramips/dts/mt7621_dlink_dir-2055-a1.dts
modified: target/linux/ramips/image/mt7621.mk
modified: target/linux/ramips/mt7621/base-files/etc/board.d/01_leds
modified: target/linux/ramips/mt7621/base-files/lib/upgrade/platform.sh
Specifications:
Board: Not known
SoC: MediaTek MT7621 Family (MT7621AT)
RAM: 256 MB (Micron 9OK17 D9PTK, should be DDR3 MT41K128M16JT-125)
Flash: 128 MB (Winbond W29N01HVSINA)
WiFi: MediaTek MT7615 Family (MT7615N x2)
Switch: 1 WAN, 4 LAN (Gigabit)
Ports: 1 USB 3.0 (front)
Buttons: Reset, WiFi Toggle, WPS
LEDs: Power (white/orange), Internet (white/orange),
WiFi 2.4G (white), WiFi 5G (white)
Notes:
Only known difference vs. the DIR-1960 A1 is that the DIR-2055 A1
doesn't have a USB activity LED
Serial port:
Tested to be identical to various DIR-8xx A1 models with a similar
enclosure/pcb design:
Parameters: 57600, 8N1, 3.3V TTL no flow control
Location: J1 header (close to the Reset, WiFi and WPS buttons)
Pinout: 1 - VCC 2 - RXD 3 - TXD 4 - GND
Did not connect VCC when using
Installation:
D-Link Recovery GUI: power down the router, press and hold the reset
button, then re-plug it. Keep the reset button pressed until the power
LED starts flashing orange, manually assign a static IP address under
the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to
http://192.168.0.1
Some modern browsers may have problems flashing via the Recovery GUI,
if that occurs consider uploading the firmware through cURL:
curl -v -i -F "[email protected]" 192.168.0.1

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).

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.
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. Signed-off-by: Sean Khan <[email protected]>

On platforms using ath10k with mac80211 'nss_redirect' enabled, a warning `ieee80211_sta_update_pending_airtime` is observered whenever traffic load is high (iperf3). Don't offload if pending queue > 1000 Signed-off-by: Sean Khan <[email protected]>
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 warning below, so it is better to remove this one.

While freeing skb in tx completion path for status reinject, inspect or vdevid mismatch, dev_kfree_skb_any() is used but when a function 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. Hence fix the issue by properly using ieee80211_free_txskb().
