+ Refresh to openwrt barrier breaker head
this now contains nearly all the patches formerly separately in cerowrt!
++ fq_codel is on by default on ALL interfaces with default quantum of 300
(yes, openwrt has obsoleted pfifo_fast!)
++ unaligned access patches, etc, etc
+ dhcp-pd SERVER support
the usual multitude of other openwrt fixes... all tested extensively
at the battlemesh conference.
+ Update to dnsmasq 2.67test2
Toke got really busy in building his own version of cero and adding
+ AQM scripts and gui
+ tahoe-lafs added (untested)
+ uftp4 updated
- no upnp/ssdp fix because I'm clueless
Yep, "AQM" gui now. /deep hat tip to toke for writing that. No need to
fiddle with any scripts now....
I guess of largest import here, underlying the gui, is that I had a
chance to deeply look at simple_qos.sh. There are several bugs in it,
that appear actually in the underlying tc subsystem.On ingress, the
priority queue was not being used properly, and a few other things
were odd in ipv6.
Out of frustration with that, and based on the data we'd got back from
cablelabs, I wrote the simplest possible rate limited fq_codel
implementation, using a reduced number of flows and a single tier of
htb only - and that works surprisingly well.
It's called "Simplest" in the new AQM screen. Give it a shot.
Secondly, the exercise of writing that and comparing it to the simple_qos script
.... seems to have exposed a bug in htb at low bandwidths.

Here I was trying at 384k up and 8Mbit down, and the middle portion of
the upload graph there is kind of... impossible. At higher rates I
haven't seen this happen.
