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?

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.

FYI, you're better off handling this in /etc/systemd/network/10-eth0.link, not as a Service Unit. This will work for systemd version > 256.

[Match]
MACAddress=00:12:34:56:78:90

[Link]
ReceiveChecksumOffload=no
TransmitChecksumOffload=no
TCPSegmentationOffload=no
TCP6SegmentationOffload=no
GenericSegmentationOffload=no
GenericReceiveOffload=no
GenericReceiveOffloadHardware=no
ReceiveVLANCTAGHardwareAcceleration=no
TransmitVLANCTAGHardwareAcceleration=no
ReceiveVLANCTAGFilter=no
TransmitVLANSTAGHardwareAcceleration=no

Or, alternatively, on Debian-based systems, using /etc/network/interfaces:

iface eth0 inet manual
        post-up /sbin/ethtool -K $IFACE gso off gro off tso off tx off rx off rxvlan off txvlan off sg off
