Subject: [net-next RFC v2] net_cls: traffic counter based on classification
 control cgroup

Hello.

It's second version of patch I already sent to netdev.

The main goal of this patch it's counting traffic for process placed to 
net_cls cgroup (ingress and egress).
It's based on res_counters and holds counter per network interfaces.

Description of patch.
It handles packets in net/core/dev.c for egress and in 
/net/ipv4/tcp.c|udp.c for ingress.
These places were chosen because we need to know also network interface.

Cgroup fs interface provides following files additional to existing 
net_cls files:
net_cls.ifacename.usage_in_bytes
Containing rcv/snd lines.
Also this patch adds to net_cls ability to handle a network device 
registration.

It could be included or excluded in compile time.
I moved the menu entry for "Control group classifier" from network/QoS to
General Option/Control Group.

I'm waiting for you comments.
