I’ve got help from CoreELEC forum. Here it is a temporary solution how to mitigate the ethernet problem:
You can change **auto_cali_idx** in dtb by command below and will stick it until next update. Then you need to run commands again.
mount -o remount,rw /flash
fdtget -t i /flash/dtb.img /ethernet@ff3f0000 auto_cali_idx
fdtput -t i /flash/dtb.img /ethernet@ff3f0000 auto_cali_idx 1
fdtget -t i /flash/dtb.img /ethernet@ff3f0000 auto_cali_idx
mount -o remount,ro /flash
reboot
It is not for Android but at least CoreELEC working.
