Hello. I have the fallowing stats when I write:
 ----tc -s -d qdisc ls dev eth1 ------
 "qdisc htb 1: r2q 1 default 99 direct_packets_stat 358 ver 3.7
 Sent 36115119 bytes 32068 pkts (dropped 0, overlimits 47848)
 backlog 24p"
1. what does backlog 24p means here ?
2. I looked over my other htb classes in eth1 and never seen overlimits greater than 0, why do I have then overlimits in htb root ?. Does anyone can tell me more explicitly what overlimits is ? 
3. And another thing if I could ask ;-) . Here is part of my htb log :


"HTB init, kernel part version 3.7
Nov 30 02:37:23 Rout-Raul kernel: HTB init, kernel part version 3.7
Nov 30 02:37:27 Rout-Raul kernel: HTB: quantum of class 10099 is small. Consider r2q change.<4>HTB: quantum of class 10099 is small. Consider r2q change.<7>htb*g j=89425972"
I have my r2q set to 1..I'm using a formula like r2q=LEAF_RATE/8*1000/1600. I was recommended by someone to use it. I really don't know why. Any suggestions ?
