[LARTC] HTB error messages

[LARTC] HTB error messages

[miller69]

Hi folks,

I'm running a linux box kernel 2.4.19 and HTB 3.6. eth0 is a 100MBit nic and
eth1 just 10MBit. The HTB setup is the following:

tc qdisc add dev eth0 root handle 1:0 htb default 10
tc class add dev eth0 parent 1:0 classid 1:1 htb rate 100mbit ceil 100mbit
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 9mbit ceil 9mbit prio
4
tc class add dev eth0 parent 1:1 classid 1:11 htb rate 89mbit ceil 100mbit
prio 1
tc class add dev eth0 parent 1:1 classid 1:12 htb rate 10kbit ceil 100kbit
prio 5

tc qdisc add dev eth1 root handle 2:0 htb default 20
tc class add dev eth1 parent 2:0 classid 2:2 htb rate 10mbit ceil 10mbit
tc class add dev eth1 parent 2:2 classid 2:20 htb rate 9mbit ceil 9mbit prio
1
tc class add dev eth1 parent 2:2 classid 2:22 htb rate 10kbit ceil 100kbit
prio 5

Now I get some error messages in /var/log/messages
*kernel: HTB init, kernel part version 3.6
*kernel: htb*g jw891655
*kernel: htb*r7 m=0
*kernel: htb*r6 m=0

and also:

 is small. Consider r2q change.<4>HTB: quantum of class 20022 is small.
Consider r2q change.

and while skipping through the logs i also found this twice:

*kernel: eth1: Too much work at interrupt, status 0x01
*kernel: HTB: mindelayP0, report it please !

Any suggestions? Some googlin' gave me a link to a patch at
http://luxik.cdi.cz/~devik/qos/htb/v3/htb_3.7_delay_bug.patch
may this help? 

Thanks in advance,
Mike.

The quantum problem is easy to solve.  Just add quantum 1500 at the 10kbit 
rate class.  More info about quantum and r2q can be found on docum.org on the 
faq pages.

Don't know.
