the below kernel options are enabled:
LOG target support
IPv6 connection tracking support,
"addrtype" address type match support
"recent" match support
the default configuration of ufw(Uncomplicated Firewall) asked them.
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.
I think the below two configurations are more basic, not special to
ufw, and netfiler.cfg lost them.
CONFIG_NETFILTER_XT_TARGET_LOG=m
CONFIG_NF_CONNTRACK_IPV6=m
Sure, but we still don't have anything within the fragments or
their descriptions that document what ufw is looking for, which
means we could remove them in the feature and unknowingly break
that functionality.
You can still add those options to the netfilter config, but we'd
be wise to add those comments, or create a ufw.scc file that (for
now), simply includes netfilter.scc and indicates that ufw requires
the options as they are in that config.

since this change has entered wrlinux kernel cache, I hope we do not
add the comment on .cfg
