    llc: Use CoDel to drop packages from the LLC queue (TODO)

    llc: Add CoDel AQM implementation
    
    This commit adds an implementation of the CoDel algorithm based on
    the reference pseudocode presented in
    http://queue.acm.org/appendices/codel.html. Instead of abstracting
    the queue itself, the implementation provides a time stamp based
    automaton which is invoked after a package has been dequeued.
