I don't know about netlink. But pfkey works in *BSD too and it is RFC'd.
So I'd say pfkey might be a bit more portable. Though netlink is definitely
more robust and extensive.

The RFCs say absolutely nothing about policy interfaces for AF_KEY,
everybody rolls their own in slightly incompatible ways.

It is therefore anything but standardized.

Yes, there's non-standardized extensions. But the point was that there are
other implementations of pfkey. And ipsec-tools racoon is an example of
a widely used application that runs in Linux and *BSD using this API. So
for the time being I'd consider having pfkey fixes as a good thing. This
pfkey dumping problem seems to be affecting many users.
