I think there should be an explicit way to enable the "kernel default
mode", i.e. the parser for this one option should consider a special
value "kernel" or so to explicitly ask for the kernel default.

I'd still prefer if we'd default to ip forwarding off, rather than ip
forwarding as kernel default, for security reasons.
