Steffen Klassert says:

====================
pull request (net-next): ipsec-next 2017-02-16

1) Make struct xfrm_input_afinfo const, nothing writes to it.
   From Florian Westphal.

2) Remove all places that write to the afinfo policy backend
   and make the struct const then.
   From Florian Westphal.

3) Prepare for packet consuming gro callbacks and add
   ESP GRO handlers. ESP packets can be decapsulated
   at the GRO layer then. It saves a round through
   the stack for each ESP packet.

Please note that this has a merge coflict between commit

63fca65d08 ("net: add confirm_neigh method to dst_ops")

from net-next and

3d7d25a68e ("xfrm: policy: remove garbage_collect callback")
a2817d8b27 ("xfrm: policy: remove family field")

from ipsec-next.

The conflict can be solved as it is done in linux-next.

Please pull or let me know if there are problems.
====================
