[][kernel][common][eth][Refactor the link polling mechanism to improve CPU usage in the USXGMII/SGMII]

[Description]
Refactor the link polling mechanism to improve CPU usage in the
USXGMII/SGMII.

The busy-wait delay functions (udelay/mdelay) may waste CPU resources.
Therefore, we need to switch to using usleep_range() instead. However,
the usleep_range function cannot be used in interrupt contexts, such as
in timer tasks. Consequently, we need to change timer tasks to
delayed_work and replace all instances of udelay with usleep_range().

Without this patch, the link polling mechanism of USXGMII/SGMII may
waste CPU resources.

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. master (will be 24.0x branch later) The next version in development

    git clone https://git.openwrt.org/openwrt/openwrt.git

3. Add MediaTek OpenWrt feed

cd openwrt
echo "src-git mtk_openwrt_feed https://git01.mediatek.com/openwrt/feeds/mtk-openwrt-feeds" >> 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. master branch

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

5. Configuration

make menuconfig

  1. 21.02 branch

    Target System -> MediaTek Ralink ARM
Subtarget -> MT7981 / MT7986 / MT7988
Target Profile -> select as needed

  2. master branch

    Target System -> MediaTek Ralink ARM
Subtarget -> Filogic 8x0 (MT798x)
Target Profile -> select as needed

6. Build

make V=s -j$(nproc)
