Like the other patch you submitted, this should go to the linux-yocto
list, but I'll reply here, since this one needs a bit more tweaking.

Adding these are fine, but if ufw needs these extra options, we should
also have a ufw.scc/.cfg fragment that can be triggered when ufw is
being built.

So either create that fragment and inside it, document the NF options
it needs, and have ufw include netfilter.scc to get the options you
are adding above.

or .. at the very least, put comments in the .cfg file above the
options indicating that they are required for ufw.
