Comment 4 for bug 1988574

Ok, so this should work with libreswan but not with freeswan.

Since the official documentation is useless:
https://libreswan.org/man/ipsec_pluto.8.html
(linked from: https://libreswan.org/man/)

Lets use this instead:
https://manpages.debian.org/unstable/libreswan/pluto.8.en.html

Which clearly states that it should be available at least in 4.3 -- if it's not in 4.5 then something has changed... And since it's in mainline and was added 2014-04-15... I don't know.

However is the netkey behavior something that neutron expects or can it just be ignored?
