iproute2's tc was updated to support the recently upstreamed cake qdisc.
Backport this canonical support from upstream into iproute2 v4.16
There is no kernel kmod/userspace tc ABI change in this release from the
previous package bump, so everyone can breath a sigh of relief.
This is largely a code style change, the exception to prove the rule:
option 'autorate_ingress' has been changed to 'autorate-ingress' to fit
in with upstream option naming expectations.
No openwrt package (e.g. sqm-scripts) has knowledge of
'autorate_ingress' thus only users who made their own scripts or used
it within the 'dangerous configuration' options of sqm-scripts will be
affected.

(cherry picked from commit a2165f936e)
The sender domain has a DMARC Reject/Quarantine policy which disallows
sending mailing list messages using the original "From" header.
To mitigate this problem, the original message has been wrapped
automatically by the mailing list software.
Bearing fruits of the latest upstreaming efforts on cake.
Changes: diffserv-llt dropped. The paper describing this DSCP
allocation has gone stale and doesn't appear used.
The userspace to kernel netlink messages for cake have been reworked in
a backwards incompatible way, so tc & cake must be bumped together this
once.

Cake in kernel space now splits stats structure handling across netlink
messages to reduce stack usage issue flagged by upstream kernel checks.
Update user space (tc) qdisc handling to understand this new regime.
Cake also reports packet overheads & compensation in a different way so
add display code for this. e.g.
'tc -s qdisc show dev eth0' reports this extra detail:
min/max transport layer size: 28 / 1500
min/max overhead-adjusted size: 65 / 1550
average transport hdr offset: 14
Cake also supports output in JSON format.
Patch is bulkier than before because a (slightly out of date - see above
stats) man page is included for reference. Better than nothing!

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.

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
