Hi Toke,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on net-next/master]

url:    https://github.com/0day-ci/linux/commits/Toke-H-iland-J-rgensen/Add-Common-Applications-Kept-Enhanced-cake-qdisc/20180427-175308
config: i386-allmodconfig (attached as .config)
compiler: gcc-7 (Debian 7.3.0-16) 7.3.0
reproduce:
        # save the attached .config to linux build tree
        make ARCH=i386 

All errors (new ones prefixed by >>):

>> net/sched/sch_cake.c:68:10: fatal error: pkt_sched.h: No such file or directory
    #include "pkt_sched.h"
             ^~~~~~~~~~~~~
   compilation terminated.

    12	 * The CAKE Principles:
    13	 *		   (or, how to have your cake and eat it too)
    14	 *
    15	 * This is a combination of several shaping, AQM and FQ techniques into one
    16	 * easy-to-use package:
    17	 *
    18	 * - An overall bandwidth shaper, to move the bottleneck away from dumb CPE
    19	 *   equipment and bloated MACs.  This operates in deficit mode (as in sch_fq),
    20	 *   eliminating the need for any sort of burst parameter (eg. token bucket
    21	 *   depth).  Burst support is limited to that necessary to overcome scheduling
    22	 *   latency.
    23	 *
    24	 * - A Diffserv-aware priority queue, giving more priority to certain classes,
    25	 *   up to a specified fraction of bandwidth.  Above that bandwidth threshold,
    26	 *   the priority is reduced to avoid starving other tins.
    27	 *
    28	 * - Each priority tin has a separate Flow Queue system, to isolate traffic
    29	 *   flows from each other.  This prevents a burst on one flow from increasing
    30	 *   the delay to another.  Flows are distributed to queues using a
    31	 *   set-associative hash function.
    32	 *
    33	 * - Each queue is actively managed by Cobalt, which is a combination of the
    34	 *   Codel and Blue AQM algorithms.  This serves flows fairly, and signals
    35	 *   congestion early via ECN (if available) and/or packet drops, to keep
    36	 *   latency low.  The codel parameters are auto-tuned based on the bandwidth
    37	 *   setting, as is necessary at low bandwidths.
    38	 *
    39	 * The configuration parameters are kept deliberately simple for ease of use.
    40	 * Everything has sane defaults.  Complete generality of configuration is *not*
    41	 * a goal.
    42	 *
    43	 * The priority queue operates according to a weighted DRR scheme, combined with
    44	 * a bandwidth tracker which reuses the shaper logic to detect which side of the
    45	 * bandwidth sharing threshold the tin is operating.  This determines whether a
    46	 * priority-based weight (high) or a bandwidth-based weight (low) is used for
    47	 * that tin in the current pass.
    48	 *
    49	 * This qdisc was inspired by Eric Dumazet's fq_codel code, which he kindly
    50	 * granted us permission to leverage.
