Merge branch 'master' of git://1984.lsi.us.es/nf-next
Pablo Neira Ayuso says:
====================
The following patchset contains Netfilter/IPVS updates for
your net-next tree, they are:
* Better performance in nfnetlink_queue by avoiding copy from the
packet to netlink message, from Eric Dumazet.
* Remove unnecessary locking in the exit path of ebt_ulog, from Gao Feng.
* Use new function ipv6_iface_scope_id in nf_ct_ipv6, from Hannes Frederic Sowa.
* A couple of sparse fixes for IPVS, from Julian Anastasov.
* Use xor hashing in nfnetlink_queue, as suggested by Eric Dumazet, from
myself.
* Allow to dump expectations per master conntrack via ctnetlink, from myself.
* A couple of cleanups to use PTR_RET in module init path, from Silviu-Mihai
Popescu.
* Remove nf_conntrack module a bit faster if netns are in use, from
Vladimir Davydov.
* Use checksum_partial in ip6t_NPT, from YOSHIFUJI Hideaki.
* Sparse fix for nf_conntrack, from Stephen Hemminger.
