This enables using the tc module m_xt.so, which uses the act_ipt kernel
module to allow tc actions based on iptables targets. e.g.
tc filter add dev eth0 parent 1: prio 10 protocol ip \
u32 match u32 0 0 action xt -j DSCP --set-dscp-class BE
Make the SHARED_LIBS parameter configurable and based on tc package
selection.
Fix a problem using the tc m_xt.so plugin as also described in
https://bugs.debian.org/868059:
Sync include/xtables.h from iptables to make sure the right offset is
used when accessing structure members defined in libxtables. One could
get “Extension does not know id …” otherwise. (See also: #868059)
Patch to sync the included xtables.h with system iptables 1.6.x. This
continues to work with iptables 1.8.2.

Replace the old 'tc' with a singleton package variant which will be used
to enable additional functionality and limit it only to tc. Non-variant
packages will only be installed during 'tiny' variant builds, hence will
be configured without extra features, thus preserving previously limited
functionality and reduced package sizes.
Also set ip-tiny as the default variant, and install 'tiny' versions of
development libraries.

Compile-based feature detection (e.g. xtables, ipset support) was broken
due to silent compilation errors in the configure script, caused by a
Makefile variable KERNEL_INCLUDE referring to kernel build headers. Use
userspace headers by setting the same "user_headers" kernel include path
as used for the iptables build.
Remove redundant or unused Build/Configure definitions from package
Makefile, including KERNEL_INCLUDE, LIBC_INCLUDE and DBM includes.
Don't pass LDFLAGS within MAKE_FLAGS as this interferes with LDFLAGS in
tc/Makefile and masks a link parameter ("-Wl,-export-dynamic"). Instead,
use standard TARGET_LDFLAGS.
Replace EXTRA_CCOPTS in MAKE_FLAGS with cleaner TARGET_CPPFLAGS, and also
drop now unneeded patch 150-extra-ccopts.patch.
Enable defining XT_LIB_DIR from Makefile, needed to set the iptables
modules directory to something other than /lib/xtables, and also add
libxtables dependency. Both are needed with working xtables detection.
Note that libxtables is also pulled in by iptables, firewall or luci, so
this change has no size impact in most cases.

The iproute2 build system links libelf support to every utility while only
the tc program actually requires libelf specific functionality.
Unfortunately the BPF ELF functionality is not confined into an own
compilation unit but added to the existing bpf.c sources of the shared
static libutil.a, causing every iproute2 applet to pick up an implicit
libelf.so dependency.
In order to avoid this requirement, patch the iproute2 build system to
create both a libutil.a and a libutil-elf.a, with the former being built
without libelf functionality and to only link the tc applet with the libelf
enabled libutil.
Finally, make the tc package depend on libelf to solve compilation errors.

iproute2's tc was updated to support the recently upstreamed cake qdisc.
Backport this canonical support from upstream into iproute2 v4.17
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.

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.
print_uint() will silently promote its variable type to uint64_t, but there
is nothing that ensures that the format string specifier passed along with
it fits (and the function name suggest to pass "%u").
Fix this by changing print_uint() to use a native 'unsigned int' type, and
introduce a separate print_u64() function for printing 64-bit values. All
call sites that were actually printing 64-bit values using print_uint() are
converted to use print_u64() instead.
Since print_int() was already using native int types, just add a
print_s64() to match, but don't convert any call sites.

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.

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.

Rename the "ip" package declaration to "ip-tiny" and let both "ip-tiny" and

the "ip" command variant while other packages can continue to depend on "ip"
without needing to enforce a specific variant.
Note that this commit does not add busybox as "ip" provider due to
the following reasons:
- The builtin Busybox ip applet cannot be added or removed at runtime
- Both "ip-tiny" and "ip-full" are able to install without file clashes even
if the busybox applet is enabled
- The system is preferring full "ip-tiny" and "ip-full" at runtime, even
if Busybox ip is still present.
