Merge git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next 

Pablo Neira Ayuso says:

====================
Netfilter updates for net-next

A small batch with accumulated updates in nf-next, mostly IPVS updates,
they are:

1) Add 64-bits stats counters to IPVS, from Julian Anastasov.

2) Move NETFILTER_XT_MATCH_ADDRTYPE out of NETFILTER_ADVANCED as docker
seem to require this, from Anton Blanchard.

3) Use boolean instead of numeric value in set_match_v*(), from
coccinelle via Fengguang Wu.

4) Allows rescheduling of new connections in IPVS when port reuse is
detected, from Marcelo Ricardo Leitner.

5) Add missing bits to support arptables extensions from nft_compat,
from Arturo Borrero.

Patrick is preparing a large batch to enhance the set infrastructure,
named expressions among other things, that should follow up soon after
this batch.

conn_reuse_mode - INTEGER
1 - default
Controls how ipvs will deal with connections that are detected
port reuse. It is a bitmap, with the values being:
0: disable any special handling on port reuse. The new
connection will be delivered to the same real server that was
servicing the previous connection. This will effectively
disable expire_nodest_conn.
bit 1: enable rescheduling of new connections when it is safe.
That is, whenever expire_nodest_conn and for TCP sockets, when
the connection is in TIME_WAIT state (which is only possible if
you use NAT mode).
bit 2: it is bit 1 plus, for TCP connections, when connections
are in FIN_WAIT state, as this is the last state seen by load
balancer in Direct Routing mode. This bit helps on adding new
real servers to a very busy cluster.
