Please note - you may want to validate whether the options used affect your setup.

Create a new service file.

Paste the required information/command in the newly created service file - please change eth0 to your desired adapter.

[Unit]

Type=oneshot
ExecStart=/sbin/ethtool -K eth0 gso off gro off tso off tx off rx off rxvlan off txvlan off sg off
RemainAfterExit=true

[Install]
WantedBy=multi-user.target

Load the new service file and enable on reboot.

systemctl daemon-reexec && systemctl daemon-reload && systemctl enable disable-offloading.service

@rcastley Very interested in this helper script. I see in your link that the PR was accepted, where can I find the script link to try it in my environment?

@crypt0rr I tried your script, and the verification command, but I got a failure response. I wonder what I did wrong?

You probably need to edit the eth0 for the identity of your specific network card - in my case it was eno2

Indeed that was it. I haven't done something like this before so I had to search how to do this. For anyone who might be in a similar position, I used ip -a and found eno1 in the list.

Thank you so much for creating this, I ran your command and it worked perfectly.
