Hello,
I don't understand why when I run:
tc class add dev eth2 parent 2:1 classid 2:85 htb rate 1024bit ceil
1mbit burst 30kb prio 5
the burst becomes 4096Mb (tc class show eth2):
class htb 2:85 parent 2:1 prio 5 rate 1024bit ceil 1000Kbit burst 4096Mb
cburst 2100b
And I've noticed if I run the same command with a different rate:
tc class add dev eth2 parent 2:1 classid 2:85 htb rate 256kbit ceil
1mbit burst 30kb prio 5
the 30kb burst appears correctly:
class htb 2:85 parent 2:1 prio 5 rate 1024bit ceil 1000Kbit burst 30kb
cburst 2100b
Thanks for your help,
JP.

That version is known to have integer overflows. Any more
revent version should fix it.
