LARTC - Feb 2004 - tc and u32 and filter documentation !

Hi List,

   Considering this QoS scenario:

   tc qdisc add dev eth0 root handle 1: htb default 12
   tc class add dev eth0 parent 1:  classid 1:1  htb rate 100kbit ceil 100kbps 
   tc class add dev eth0 parent 1:1 classid 1:10 htb rate  30kbit ceil 100kbps
   tc class add dev eth0 parent 1:1 classid 1:11 htb rate  10kbit ceil 100kbps
   tc class add dev eth0 parent 1:1 classid 1:12 htb rate  60kbit ceil 100kbps
   tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 \
      match ip src 1.2.3.4 match ip dport 80 0xffff flowid 1:10
   tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 \
      match ip src 1.2.3.4 flowid 1:11
   tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 \
      match ip dport 80 0xffff flowid 1:10

   Here follows my doubts:

   Where will be classified a packet coming from 1.2.3.4 port 80 ?
   
( just to be sure ''cuz I''m making a very simple QoS tutorial
in portuguese brazilian  )

   Where ca I find a full tc syntax ( I already have the manpage ) and u32 
filter documentation ?

Atenciosamente,

Most of the options depends on what you do with the tc command: adding 
filters, qdiscs, classes, ...
