++Intermediate queueing device support

++ The imq device(s) is used as placeholder for QoS queueing disciplines.
++ Every packet entering/leaving the ip stack can be directed through

++ This allows you to treat network devices as classes and distribute
++ bandwidth among them. Iptables is used to specify through which imq
