developer fb7d05389b [][CRITICAL][openwrt-25][MAC80211][WiFi7][mt76: mt7996: Fix spinlock usage to prevent AP panic] 
[Description]
Update MP4.3 critical patches - 20260811

mt76:
mtk: mt76: mt7996: Fix spinlock usage to prevent AP panic

AP panic occurs due to Asynchronous SError Interrupt during WiFi
operations in specific test scenarios with WPA2-WPA3-PSK-CCMP security
on 2.4G band.

Feature: Stability

[Root Cause]
Improper spinlock usage with spin_lock_bh instead of spin_lock_irqsave
leads to potential race conditions and interrupts during critical
sections.

[Solution]
Replace spin_lock_bh with spin_lock_irqsave and spin_unlock_bh with
spin_unlock_irqrestore to ensure proper locking and interrupt
handling, preventing race conditions and AP panic.

Brief introduction for using MediaTek released OpenWrt SDK

1. Build system setup

2. Clone vanilla OpenWrt

Currently two release branches are supported:

  1. 21.02 This is the current in-use branch

    git clone -b openwrt-21.02 https://git.openwrt.org/openwrt/openwrt.git

  2. 24.10 This is the current in-use branch

    git clone -b openwrt-24.10 https://git.openwrt.org/openwrt/openwrt.git

3. Add MediaTek OpenWrt feed

cd openwrt
echo "src-git mtk_openwrt_feed https://github.com/mediatek/mtk-openwrt-feeds.git" >> feeds.conf.default
./scripts/feeds update -a
./scripts/feeds install -a

4. Apply MediaTek OpenWrt files and patches

  1. 21.02 branch

    cp -af ./feeds/mtk_openwrt_feed/21.02/files/* .
cp -af ./feeds/mtk_openwrt_feed/tools .
for file in $(find ./feeds/mtk_openwrt_feed/21.02/patches-base -name "*.patch" | sort); do patch -f -p1 -i ${file}; done
for file in $(find ./feeds/mtk_openwrt_feed/21.02/patches-feeds -name "*.patch" | sort); do patch -f -p1 -i ${file}; done

  2. 24.10 branch

    cp -af ./feeds/mtk_openwrt_feed/24.10/files/* .
for file in $(find ./feeds/mtk_openwrt_feed/24.10/patches-base -name "*.patch" | sort); do patch -f -p1 -i ${file}; done
