Updating the proxmox kernel will require you to remove this and potentially reapply

Descripton

As part of proxmox 8.0 the realtek drivers are having issues where after a certain amount of time the node will go offline and lose connectivity.
Here are the steps I took with a no-subscription repo.
to know if you could be affected by this issue, log into your proxmox host, either via ssh or keyboard and display and run:
lspci -nnk
if you are affected, you should see a Ethernet controller from Realtek Semiconductor Co. using the r8169 driver
for example
01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 15)
        Subsystem: Dell RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [1028:07a3]
        Kernel driver in use: r8169
        Kernel modules: r8169

Walkthrough

modify the repository source list. These repositories provide packages and updates for your system.
vi /etc/apt/sources.list
deb http://ftp.us.debian.org/debian bookworm main contrib non-free non-free-firmware
deb http://ftp.us.debian.org/debian bookworm-updates main contrib non-free non-free-firmware
# security updates
deb http://security.debian.org bookworm-security main contrib non-free non-free-firmware
deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription

After modifying the sources.list file we need to make sure the system updates the package list from the repositories
apt update
Heres where most issues came up for me, we need to install the pve-headers pacakge. because without it, we will have issues compiling the realtek-dkms package.
The -dkms suffix indicates that it's a Dynamic Kernel Module Support package, which means it can be automatically rebuilt whenever the kernel is updated.
When you install this package, it uses the kernel headers (provided by pve-headers) to build and install the Realtek network card driver as a kernel module.
apt install pve-headers -y
Install the Realtek 8168 network card driver as a Dynamic Kernel Module Support package. It can automatically rebuild the driver when the kernel is updated.
apt install r8168-dkms -y
Then, for good measure I made sure my other packages were updated.
apt upgrade -y
blacklist the 8169 driver from being loaded
echo blacklist r8169 >> /etc/modprobe.d/blacklist-r8169.conf
Once all of  this is completed we are going to update our GRUB to have some specific kernel parameters for our realtek driver
sed -i 's/GRUB_CMDLINE_LINUX=""/GRUB_CMDLINE_LINUX="r8168.aspm=0 r8168.eee_enable=0 pcie_aspm=off loglevel=3"/' /etc/default/grub
Finally, we are are going to refresh the boot configuration for Proxmox and reboot.
proxmox-boot-tool refresh
reboot -n
