Hi,
Is 10Mbits/s considered a high data rate? Assuming that it is:
I'm just a user of openwrt using a pre-supplied image. How would I check
without access to the kernel config?
I have tried:
cat /proc/timer_list (based on http://elinux.org/High_Resolution_Timers)
but that file is not present.
Given that I would probably assume that it is not enabled. So unless enabling
it is a relatively simple task, which given that it a kernel thing probably
means recompiling the kernel which is probably something I am unable to do. I
want the feature but not so badly that I would be willing to go to that length
for it.

Hi,
Shaping with high datarates requires the use of the HR Timers. I once
had problems like that. Is it enabled in your kernel config?

Hi,
Yeah, that doesn't seem to work:
$ tc qdisc add dev eth0 root pfifo_fast
RTNETLINK answers: No such file or directory
It looks right, but again it doesn't work the way you would expect.
The reason I want it removed is because something is screwing the shaping on
eth0.2. I always get 7Mb down and 1Mb up no matter what I set the values
(ridiculously high or low). I have tried doing it manually
(http://lartc.org/) and using wshaper. Either that or I have a buggy
release (14.07, r42625). My internet without shaping is 65Mb down and 10Mb
up.
I like fq_codel (I run where I can), but it won't make as much difference
unless I get the shaping right because the link to the modem is 100Mb/s
(which being owned by the ISP probably has a massive queue running fifo) and
only the connection after that is 10Mb/s. I want fq_codel (on openwrt) to be
in charge of queue not the modem running fifo.

I'm curious as to why you are trying to remove fq_codel? have you run into
a place where it hurts you? or are you just trying to compare it with
pfifo_fast?

Subject: [OpenWrt-Users] Remove fq_codel from eth0
Hi,
I cannot remove the fq_codel qdisc from the eth0 device.
I have tried:
tc qdisc del dev eth0 root
However it responds with:
RTNETLINK answers: No such file or directory
However:
tc -s qdisc show dev eth0
Responds with:
qdisc fq_codel 0: root refcnt 2 limit 1024p flows 1024 quantum 300 target
5.0ms interval 100.0ms ecn
Sent 152870410415 bytes 180254077 pkt (dropped 412, overlimits 0 requeues

maxpacket 1514 drop_overlimit 0 new_flow_count 545433 ecn_mark 4
new_flows_len 0 old_flows_len 0
How do get rid of it or replace it with pfifo_fast so it basically
doesn't do anything?
I am using Barrier Breaker.

spaceman
