I was conflicted when I was about to put Fixes tag on this patch because
it could either be b4869aa2f881 that you mentioned above, or 6f12fa7755301
("vrf: mark skb for multicast or link-local as enslaved to VRF"). So, I
decided not to put it, but may be I should so that this is qualified to
be queued to stable?
