[10/10] QoS: Use CONNMARK to mark connections in connection tracking
Commit Message
This patch modifies the connection tracking in that ways that
it sets a connection mark which will be retrieved when a packet
is being redirected to the IFB interface.
This way, we can use classification without having the packet
being sent through iptables first.
