[][kernel][mt7988][eth][Refactor QDMA rate limit for the TOPS]

[Description]
Refactor QDMA rate limit for the TOPS.

Due to the previous method, some of phylink's functions for getting
the maximum speed for rate adaptation were removed. Therefore, it
causes the GMAC to be unable to configure the speed correctly when
the PHY is running in rate adaptation mode.

Without this path, the GMAC is unable to configure the speed correctly
when the PHY is running in rate adaptation mode.

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
