    [NET]: Add IFB (Intermediate Functional Block) network device. · 253af423
    Jamal Hadi Salim authored
    A new device to do intermidiate functional block in a system shared
    manner.  To use the new functionality, you need to turn on
    qos/classifier actions.
    
    The new functionality can be grouped as:
    
    1) qdiscs/policies that are per device as opposed to system wide.  ifb
    allows for a device which can be redirected to thus providing an
    impression of sharing.
    
    2) Allows for queueing incoming traffic for shaping instead of
    dropping.
    
    Packets are redirected to this device using tc/action mirred redirect
    construct. If they are sent to it by plain routing instead then they
    will merely be dropped and the stats would indicate that.
