Ubuntu 16.04
The "allow_unsupported_sfp=1,1" they suggest does not work in the kernel I use. Only allow_unsupported_sfp=1
/etc/default/grub:
GRUB_CMDLINE_LINUX=" ixgbe.allow_unsupported_sfp=1"
update-grub
cat /etc/modprobe.d/ixgbe.conf
options ixgbe allow_unsupported_sfp=1
dpkg-reconfigure initramfs-tools
