Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next 

Steffen Klassert says:

====================
pull request (net-next): ipsec-next 2018-10-18

1) Remove an unnecessary dev->tstats check in xfrmi_get_stats64.
   From Li RongQing.

2) We currently do a sizeof(element) instead of a sizeof(array)
   check when initializing the ovec array of the secpath.
   Currently this array can have only one element, so code is
   OK but error-prone. Change this to do a sizeof(array)
   check so that we can add more elements in future.
   From Li RongQing.

3) Improve xfrm IPv6 address hashing by using the complete IPv6
   addresses for a hash. From Michal Kubecek.

Please pull or let me know if there are problems.
