For 4.14.y cherry-pick:

Acked-by: Willem de Bruijn <willemb@xxxxxxxxxx>

Might be good to point out that this is not only a clean cherry-pick
of the one-line patch, but has to include part of commit a818f75e311c
("net: ipv6: Hook into time based transmission") to plumb the
sockcm_cookie. The rest of that patch is not a candidate for stable,
so LGTM.
