Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says:
====================
This pull request is intended for net-next and contains the following changes:
1) Remove a redundant check when initializing the xfrm replay functions,
from Ulrich Weber.
2) Use a faster per-cpu helper when allocating ipcomt transforms,
from Shan Wei.
3) Use a static gc threshold value for ipv6, simmilar to what we do
for ipv4 now.
4) Remove a commented out function call.
