CONFIG_NETFILTER=y is the only possible non-disabled setting, as it's
a boolean.
All that is enabling is the hooks, and it's not possible to provide
netfilter at all without the hooks being compiled into the kernel
image.
Fedora by default is also probably installing several defauly
netfilter rules, make sure to remove them.
