Same errors here.
I see that proxmox has had problems with Intel NIC for many years.
What card should I buy for this to work properly?
Or maybe that's just the way proxmox is?

I219-V,I218-V chipet drivers are shitty, not only on proxmox, same on xcp-ng for example

personnaly I'm using mellanox connect-x in production without any problem.

ethtool -K eth0 tx off rx off

Disabling TCP checksum offloading worked for me

Great! It helped! Thanks a lot!

Also wanted to give a big thank you for

This seems to have solved the hardware hangups and DRASTICALLY improved the network latency for the webapps I am running.

I presume that you executed the command in the PVE node, not inside the VM, correct? Moreover, what other guests did you have in the node? I have a mix of VMs and LXCs and this behaviour only happens where I have VMs. Would that be your case, too?
