Hi Simon,
Today's linux-next merge of the ipvs-next tree got a conflict in between commit 264640fc2c5f4f ("ipv6: distinguish frag queues by device for multicast and link-local packets") from the net tree and commit 029f7f3b8701c ("netfilter: ipv6: nf_defrag: avoid/free clone operations") from the ipvs-next tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
