[][kernel][common][eth][Add Ethernet jumbo frame support]

[Description]
Add Ethernet jumbo frame support.

Please ensure that all network devices involved in
the transmission, including network cards, switches,
PCs etc., support jumbo frames.

The jumbo frame settings for all related devices should
be consistent, including the MTU size and the enabled
status; otherwise, it will lead to communication errors
or packet loss.

How to enable jumbo frame?
MT7986/81: Change MTK_MAX_RX_LENGTH from default to
MTK_MAX_RX_LENGTH_2K.
MT7988: Change MTK_MAX_RX_LENGTH from default to
MTK_MAX_RX_LENGTH_9K.

Without this patch, jumbo frame transmission cannot be
supported.

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)
