e1000e network issue on Proxmox

The ethtool configuration is about disabling HW offloading (or acceleration if you will) of certain features. Turning them off just moves the responsibility to software instead (which Linux have done for ages). I'm not aware that this changes anything related to data integrity.
 
Hello, I'm facing the same issue, and I don't know why but the post-up command did nothing.
So I asked Claude.ai to write me a script to simulate a physical unplug replug of the cable.

This is what it did.
Can anyone have a look and criticize ? :D
what do you think ?

thx a lot

I applied this to my interface file, reboot since, and had the problem yesterday, so it seems it does not work for me :/
