There has been recent significant activity with the cake qdisc of late
Some of that effort is related to upstreaming to kernel & iproute2
mainline but we're not quite there yet. This commit teaches tc how to
activate and interprete the latest cake operating modes, namely:
ingress mode: Instead of only counting packets that make it past the
shaper, include packets we've decided to drop as well, since they did
arrive with us on the link and took link capacity.
This mode is more suitable for shaping the ingress of a link
(e.g. from ISP) rather than the more normal egress.
ack-filter/ack-filter-aggressive: Filter excessive TCP ACKS. Useful in
highly assymetric links (downstream v upstream capacity) where the
majority of upstream link capacity is occupied with ACKS for downstream
traffic.

Cake AQM is experimenting with a codel/blue hybrid AQM COBALT instead
of just using codel alone. This patch updates tc to cope with some new
stats produced by COBALT.

Add cake support to 'tc' in iproute2
- Use a patch to modify tc instead of adding a new tc-adv package.
Patch creates q_cake.c that matches commit 3314230bc4
- Do not include the other things from tc-adv (cake0, cake2, pie etc.).
V2 - KDB Small update to base on latest cake tc changes (wash option
deprecated)
V3 - KDB Move kmod-sched-cake package to kernel as is kernel related
v4 - KDB Split into individual patches, tc & kmod
