====================
pull request (net-next): ipsec-next 2017-12-15

1) Currently we can add or update socket policies, but
   not clear them. Support clearing of socket policies
   too. From Lorenzo Colitti.

2) Add documentation for the xfrm device offload api.
   From Shannon Nelson.

3) Fix IPsec extended sequence numbers (ESN) for
   IPsec offloading. From Yossef Efraim.

4) xfrm_dev_state_add function returns success even for
   unsupported options, fix this to fail in such cases.
   From Yossef Efraim.

5) Remove a redundant xfrm_state assignment.
   From Aviv Heller.

Please pull or let me know if there are problems.
