pull request (net-next): ipsec-next 2017-12-22

[Steffen Klassert <steffen.klassert@secunet.com>]

1) Separate ESP handling from segmentation for GRO packets.
   This unifies the IPsec GSO and non GSO codepath.

2) Add asynchronous callbacks for xfrm on layer 2. This
   adds the necessary infrastructure to core networking.

3) Allow to use the layer2 IPsec GSO codepath for software
   crypto, all infrastructure is there now.

4) Also allow IPsec GSO with software crypto for local sockets.

5) Don't require synchronous crypto fallback on IPsec offloading,
   it is not needed anymore.

6) Check for xdo_dev_state_free and only call it if implemented.
   From Shannon Nelson.

7) Check for the required add and delete functions when a driver
   registers xdo_dev_ops. From Shannon Nelson.

8) Define xfrmdev_ops only with offload config.
   From Shannon Nelson.

9) Update the xfrm stats documentation.
   From Shannon Nelson.

Please pull or let me know if there are problems.

Thanks!
