What do you need that for? Please explain in the commit log and in an
inline comment.

I'm not sure what needs to be further explained. The fact that nftables
can be provided either by the iptables package or by the nftables
package ? Baruch, could you clarify what additional explanations you
are looking for ?
Thanks!

I had the impression that BR2_PACKAGE_IPTABLES_NFTABLES itself depends on
BR2_PACKAGE_NFTABLES to provide nftables support. I see now that this is not
the case. Still, the fact that --enable-nftables enables support for both
packages looks strange. So I think that a comment that says something like
"iptables and nftables both provide compatible API" would be nice.
BTW, what happens when both BR2_PACKAGE_NFTABLES and
BR2_PACKAGE_IPTABLES_NFTABLES are enabled? Do both coexist? If they do, I see
no way for keepalived to know which library to link against. iptables will
always build before keepalived because it optionally depends on
BR2_PACKAGE_IPTABLES anyway. But nftables might not build before keepalived in
that case.

I guess the configure script will prefer one over the other if both are available.
If the configure script prefers iptables over nftables, then the proposed patch
looks good to me. If, however, the configure script prefers nftables over
iptables, then the patch is wrong because the keepalived would be built
differently depending on whether nftables is built first or not.
Regards,
Arnout

I sent a v2, nftables support in keepalived depends on libmnl and
libnftnl, it does not depend on iptables/nftables applications.
