Steffen Klassert says:

====================
pull request (net): ipsec 2016-12-01

1) Change the error value when someone tries to run 32bit
   userspace on a 64bit host from -ENOTSUPP to the userspace
   exported -EOPNOTSUPP. Fix from Yi Zhao.

2) On inbound, ESN sequence numbers are already in network
   byte order. So don't try to convert it again, this fixes
   integrity verification for ESN. Fixes from Tobias Brunner.

Please pull or let me know if there are problems.
