# Attached is a work-around for the in-kernel driver that is as unhacky as I can make it.

# filename: r8169_disable_msi

# Drop it in /etc/initramfs-tools/scripts/init-top and chmod a+x it. Add 'r8169_disable_msi'
# to your kernel command line (/etc/default/grub, GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
# usually.) 

# Remember to update-initramfs and update-grub as necessary.

# sudo update-initramfs -c -k $(uname -r)
# sudo update-grub
# reboot

# For the moment it disables MSI on everything with the ID 0x10ec:0x8168, as there seems to
# be no way to get the MAC version from userspace - and certainly not before the driver is
# loaded. Other PCI IDs may need adding..

# Still hoping we can cherry pick the in-driver workaround for bionic...?
