[LARTC] HTB burst/cburst decremented by one

[LARTC] HTB burst/cburst decremented by one

[DervishD]

    Hi all :)

    If I set the burst/cburst parameter to, let's say, 1500, the
command "tc -s -d class show dev eth0" says that the value is 1499b/8
instead of the (correct?) 1500b/8.

    Is this right or am I doing anything wrong?

    Many thanks in advance :)

No, this is related to an integer division loosing precision in some
cases. I'm looking into a fix, but it might take a while.

    OK, thanks a lot :) In the meantime I'll just add "1" by hand to
get the numbers I really want ;)
