Backport from Linux Kernel v5.12, commit: 9f4ad9e425

Prebuild module

https://github.com/fbelavenuto/arpl-modules

Eg: https://github.com/fbelavenuto/arpl-modules/blob/main/geminilake-4.4.180/igc.ko

Build

1. Setup develop environment

Prepare Environment

Refer: https://help.synology.com/developer-guide/getting_started/prepare_environment.html

Assume platform=geminilake, version=7.1, working directory is /synology-toolkit

Now the build env is /synology-toolkit/build_env/ds.geminilake-7.1

Enter chrooot

sudo chroot /synology-toolkit/build_env/ds.geminilake-7.1

Clone source code

cd /usr/src/
git clone https://github.com/jim3ma/synology-igc.git

2. Build module

cd /usr/src/synology-igc/
make -C /usr/local/x86_64-pc-linux-gnu/x86_64-pc-linux-gnu/sys-root/usr/lib/modules/DSM-7.1/build M=$PWD modules

3. Load module

Copy igc.ko to target machine

Find i225/i226 pci device

03:00.0 Ethernet controller: Intel Corporation Ethernet Controller I225-V (rev 03)

insmod igc.ko debug=16 # enable debug log
echo igc > /sys/bus/pci/devices/0000:03:00.0/driver_override
echo 0000:03:00.0 > /sys/bus/pci/drivers_probe
ip link set up eth1 # in my machine, the nic name is eth1

TODO

  1. tc support
  2. igc: Enable internal i225 PPS - 64433e5bf4
