Merge branch 'master' of git://1984.lsi.us.es/nf-next
Pablo Neira Ayuso says:
====================
The following patchset contains Netfilter and IPVS updates for
your net-next tree, most relevantly they are:
* Add net namespace support to NFLOG, ULOG and ebt_ulog and NFQUEUE.
The LOG and ebt_log target has been also adapted, but they still
depend on the syslog netnamespace that seems to be missing, from
Gao Feng.
* Don't lose indications of congestion in IPv6 fragmentation handling,
from Hannes Frederic Sowa.i
* IPVS conversion to use RCU, including some code consolidation patches
and optimizations, also some from Julian Anastasov.
* cpu fanout support for NFQUEUE, from Holger Eitzenberger.
* Better error reporting to userspace when dropping packets from
all our _*_[xfrm|route]_me_harder functions, from Patrick McHardy.
