Not sure if this is the correct place to open this issue. With Rock PI 4C containing RK3399 chip, the network has lots of error if TCP offload is not disabled.
Workaround:
Disable it with (immediate effect + persistent in reboot)
cat <<EOF | sudo tee /etc/network/if-up.d/disable-offload
#!/bin/sh
# TCP offloading must be disabled because of RK3399 bug.

/sbin/ethtool -K eth0 rx off tx off
EOF
sudo chmod 755 /etc/network/if-up.d/disable-offload
sudo /etc/network/if-up.d/disable-offload
Long-term solution:
Correct the network driver to allow TCP offload? I guess the workaround will affect the network performance and CPU negatively.
