[RFC][PATCH 0/5] IPVS full NAT support + netfilter 'ipvs' match support

[Hannes Eder]

The following series is aiming at adding full NAT support to IPVS.  The
approach is via a minimal change to IPVS (make friends with nf_conntrack)
and adding a netfilter matcher (xt_ipvs + libxt_ipvs).

Example usage:

% ipvsadm -A -t 192.168.100.30:8080 -s rr
% ipvsadm -a -t 192.168.100.30:8080 -r 192.168.10.20:8080 -m
# ...

# SNAT for VIP 192.168.100.30:8080
% iptables -t nat -A POSTROUTING -m ipvs --vaddr 192.168.100.30/32 --vport 8080 \
> -j SNAT --to-source 192.168.10.10
