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Patch is bulkier than before because a (slightly out of date - see above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!

print_int used 'int' type internally, whereas print_uint used 'uint64_t'
These helper functions eventually call vfprintf(fp, fmt, args) which is
a variable argument list function and is dependent upon 'fmt' containing
correct information about the length of the passed arguments.
Unfortunately print_int v print_uint offered no clue to the programmer
that internally passed ints to print_uint were being promoted to 64bits,
thus the format passed in 'fmt' string vs the actual passed integer
could be different lengths. This is even more interesting on big endian
architectures where 'vfprintf' would be looking in the middle of an
int64 type. Symptoms of this included tc qdisc showing bizarre values
for a variety of fields across a variety of qdiscs (e.g. refcnt, flows,
quantum)
print_u/int now stick with native int size.
A similar patch has been sent upstream.
Fixes FS#1425

This replaces the current patches used to make the kernel headers
compatible with musl with the version which was accepted upstream. This
is included in upstream kernel 4.15.
This was compile tested with iproute2 build on all supported kernel
versions with musl and one one with glibc.

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

iproute2-4.0 had connmark support added by nbd. This does not work
with 4.x kernels. iproute2-4.3 is the latest version and has his
changes mainlined. This patch updates the package to iproute2-4.3
and fixes the patches so that it compiles. This should resolve
ticket #21374.

The most significant change from the previous version is the trimming of

had vanished. That section of the patch was removed.

iproute2 includes "sanitized" linux kernel headers, which work fine for uClibc, however
with musl there is some header conflict, principally some ipv6 structure redefinition. This
patch removes <linux/in6.h> from include/linux/if_bridge.h to solve the problem.
