Hi,
I am currently working on the TC.
I have seen some behaviour which seems to be odd.
I know someone in the mailing list would have seen this problem or may
have some fix for this problem.
When I try to include u32 filters with different priority or pref, I
could see the filters being set on all the priority's irrespective of
the priority number.
See my sample script below and the command "tc filter show dev eth1
parent yy:".
Can anyone suggest a fix for this. Is that a bug in just displaying - if
so has it been fixed or is there any fix available on the net.
Sample Script:
#! /bin/sh
tc qdisc add dev eth1 root handle 1:0 htb r2q 1
tc class add dev eth1 parent 1:0 classid 1:fffe htb rate 100mbit
tc filter add dev eth1 parent 1:0 prio 1 protocol ip u32
tc filter add dev eth1 parent 1:0 prio 1 handle ffe:0 protocol ip u32
divisor 256
tc filter add dev eth1 parent 1:0 prio 1 protocol ip u32 ht 800:: match
u32 \

Please can anyone tell me what to do.
Thanks
