Hung networking hardware in Proxmox

I one day woke up in the morning to the following error on my Proxmox server:

Apr 20 00:06:20 pve kernel: e1000e 0000:00:1f.6 eno1: NIC Link is Down

After some digging, I added the following to the /etc/network/interfaces file. Haven’t seen that error again in at least a few months:
