At a certain point using /etc/network/options got deprecated. I'm not
sure if this goes for whatever version of debian you're using but the
proper way to enable it in newer versions would be via sysctl. There
should already be a value listed in /etc/sysctl.conf that you just
need to uncomment. Then it gets set like you want it on every boot.
You can use the sysctl utility to set it yourself.
