I went for a test drive of openwrt DESIGNATED DRIVER (Bleeding Edge,
A) I bricked the archer c7 v2. No idea why.
B) I got a sorta working linksys 1200ac build.
The bad news: Any attempt to run 2 or more copies of netperf's
netserver on the 1200ac router with the default qdiscs (mq +
fq_codel), at line (gbit) rate, result in it locking up *for any other
traffic, including ping* until the first netperf is more or less
complete. I fear the underlying driver is frightfully overbuffered,
or has another problem.
(needs BQL, too)
The still bad news: cake works in both directions for a while longer,
then goes boom similarly.
The somewhat good news:
cake "shaped" to 900mbit on inbound and outbound to the router - does
not lock up the router. It merely runs out of cpu, but still does
manage quite respectable throughput in both directions while doing
so. Note, I did not say "latency".
As usual there is some flent data in that dir if you want to draw your
I was not in a position to actually test traffic through the router
(because I had the archer setup to do that)
I wouldn't draw any conclusions from this. Well, a safe conclusion,
is: don't install this build.

Simple patch for this, It involves invoking a deity.
