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.

Support for Transformation(XFRM) user configuration interface
like IPsec used by native Linux tools.
If unsure, say Y.
config XFRM_SUB_POLICY
bool "Transformation sub policy support"
depends on XFRM
---help---
Support sub policy for developers. By using sub policy with main
one, two policies can be applied to the same packet at once.
Policy which lives shorter time in kernel should be a sub.
If unsure, say N.
config XFRM_MIGRATE
bool "Transformation migrate database"
depends on XFRM
---help---
A feature to update locator(s) of a given IPsec security
association dynamically. This feature is required, for
instance, in a Mobile IPv6 environment with IPsec configuration
where mobile nodes change their attachment point to the Internet.
If unsure, say N.
config XFRM_STATISTICS
bool "Transformation statistics"
depends on INET && XFRM && PROC_FS
---help---
This statistics is not a SNMP/MIB specification but shows
statistics about transformation error (or almost error) factor
at packet processing for developer.
If unsure, say N.

---help---
PF_KEYv2 socket family, compatible to KAME ones.
They are required if you are going to use IPsec tools ported
from KAME.
Say Y unless you know what you are doing.
config NET_KEY_MIGRATE
bool "PF_KEY MIGRATE"
depends on NET_KEY
select XFRM_MIGRATE
---help---
Add a PF_KEY MIGRATE message to PF_KEYv2 socket family.
The PF_KEY MIGRATE message is used to dynamically update
locator(s) of a given IPsec security association.
This feature is required, for instance, in a Mobile IPv6
environment with IPsec configuration where mobile nodes
change their attachment point to the Internet. Detail
information can be found in the internet-draft
<draft-sugimoto-mip6-pfkey-migrate>.
If unsure, say N.
