Subject: [PATCHv2 net-2.6.25 0/3] PSPacer qdisc module

Hi all,

This is the 2nd version of PSPacer patches.

PSPacer (Precise Software Pacer) is a qdisc module which realizes 
precise transmission bandwidth control. It makes bursty traffic which is 
often generated by TCP smooth without any special hardware.
For your information, please see my previous post:
http://marc.info/?l=linux-netdev&m=119570861526290&w=2

Changes:
* checked by the checkpatch.pl script.
* introduced struct gaphdr.
* removed the HTB-way of using a "direct class".
* removed unnecessary skb_reserve() and magic values in alloc_gap_packet().
* added a proper check when skb_clone() fails in psp_dequeue().
* used qdisc_tree_decrease_qlen() in psp_graft().

Usage:
    # tc qdisc add dev eth0 root handle 1: psp default 1
    # tc class add dev eth0 parent 1: classid 1:1 psp rate 500mbit
    # tc qdisc add dev eth0 parent 1:1 handle 10: pfifo

Patches:
[1/3] PSPacer kernel part
[2/3] PSPacer tc part
[3/3] PSPacer tc man page

Best regards,
Ryousei Takano
