The last two parameters passed between user space tc and kernel space
sched-cake were transposed due to a merge mistake in a parameter header
file.
As such, using a packet overhead figure was likely to set cake to wash
packet DSCP values. Similarly, the DSCP wash flag was used as an offset
to the displayed packet overhead value.

Follow upstream cake:
diffserv3: a simple 3 tin classifier more in line with sqm-scripts
defaults for other qdisc algorithms.
defaults: default qdisc options are now diffserv3 and triple-isolate.

Track upstream changes, incl changes in packet overhead accounting
(automatically taking care of linux' packet sizing knowledge),
improvements to triple isolated DRR handling (new flow dominance),
statistics tweak & allow more packet drops in stressed conditions.
Under tests this has significantly improved latency control under
'many flows to one' scenarious as is typical of bittorrent and MS
Windows update.
I also restored 'DSCP washing' functionality in my repo which follows
upstream closely (like a hawk!) with tc keywords 'wash/nowash'. This
allows cake to limit/control packets in bands determined by a packet's
DSCP but to clear those DSCP bits on qdisc egress. This functionality
was originally removed as part of an attempt to push cake into the
kernel, which hasn't actually happened as yet.
A matching commit is required to iproute2/tc to support the new overhead
handling, keyword changes as well as the 'wash/nowash' tweak.

* Change git packages to xz
* Update mirror checksums in packages where they are used
* Change a few source tarballs to xz if available upstream
* Remove unused lines in packages we're touching, requested by jow- and blogic
* We're relying more on xz-utils so add official mirror as primary source, master site as secondary.
* Add SHA256 checksums to multiple git tarball packages

COBALT is a hybrid codel/blue algo combining best elements of both.
Exhibits improved behaviour in presence of abuse from unresponsive flows
handled by 'blue', whereas responsive flows are still handled by codel.

In company networks everything except the http and https protocol is
often causes problems, because the network administrators try to block
everything else. To make it easier to use LEDE in company networks use
the https/http protocol for git access when possible.

Add 'cake' qdisc kernel module package.
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, kmod & tc
