Realtek r8168 Driver for Proxmox VE Kernel version 6.8

Blacklist r8169 kernel driver for 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

Run following commands to download from source and compile, install the driver:

apt-get install debhelper-compat dh-dkms

mkdir r8168_v3 && cd r8168_v3
wget http://deb.debian.org/debian/pool/non-free/r/r8168/r8168_8.055.00-1.debian.tar.xz
wget http://deb.debian.org/debian/pool/non-free/r/r8168/r8168_8.055.00.orig.tar.bz2
wget http://deb.debian.org/debian/pool/non-free/r/r8168/r8168_8.055.00-1.dsc
dpkg-source -x r8168_8.055.00-1.dsc
cd r8168-8.055.00/
dpkg-buildpackage
dpkg -i ../r8168-dkms_8.055.00-1_all.deb

Or download the driver directly and install

wget http://ftp.debian.org/debian/pool/non-free/r/r8168/r8168-dkms_8.053.00-1_all.deb
dpkg -i r8168-dkms_8.053.00-1_all.deb
