This patch makes sch_cake's gso/gro splitting configurable
from userspace.
To disable breaking apart superpackets in sch_cake:

(cherry picked from commit 3e8a9389961cd866b867740a2f71c2a0af97ab56)
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.

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.

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.

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.

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
"ip-full" provide the virtual "ip" package. This allows users to freely choose
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.
