Fix Intel e1000e error

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

Create a new service file.

nano /etc/systemd/system/disable-offloading.service

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

[Unit]
Description=Disable NIC offloading
After=network.target

[Service]
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

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.

@profucius

@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?

The source for my PR is available here - https://raw.githubusercontent.com/rcastley/ProxmoxVED/refs/heads/main/tools/pve/nic-offloading-fix.sh

So you could run the following from your PVE shell:

bash -c "$(curl https://raw.githubusercontent.com/rcastley/ProxmoxVED/refs/heads/main/tools/pve/nic-offloading-fix.sh)"

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

Just confirming that this script worked perfectly for me too!

Thank you @profucius and @chrismaddahl ... just waiting for community-scripts to approve and merge 👍

Yes, same here. Problem has started happening again. Very frustrating :(

This also seems to happen for the Intel I225-LM 2.5 Network Cards too :-( Could the script be updated potentially to cover the model as well?

Just updated one of my hosts here, lets see what it does..

As the author of the Proxmox Helper Script ... I am still up and running on my Intel NUC

root@pve:~# pveversion
pve-manager/8.4.5/57892e8e686cb35b (running kernel: 6.8.12-12-pve)
root@pve:~# uptime
 22:26:50 up 3 days,  7:56,  1 user,  load average: 0.23, 0.24, 0.11

If anyone find any nuances that need to be added ... then please reply here and I can update the Helper Script ... but so far not one issue on my setup.

I did find I had to the run the post install Helper Script again as I was getting the nag screen.

Same on the NAG screen. The issue has not (yet) popped up after upgrading to 8.4.5 as shown in my previous post.

Thanks a lot for this post. It made a huge difference. Solved an issue with Proxmox 8.5.x on an old-ish server.
