question about major:minor numbers

Hi,
the documentation says "[the major number of a class] must be unique
within a egress or ingress setup. The minor number must be unique within
a qdisc and his classes." 

What is meant by "setup"? Does that include all qdiscs attached to any
network device? Ie, if I have a qdisc attached to eth0 and another
attached to eth1, do the major numbers I use have to be different at all
or could I use the same number structure in eth0 and eth1? 

Short example to explain:
 tc qdisc add dev eth0 root handle 1: htb default 13
 tc class add dev eth0 parent 1: classid 1:1 htb rate 100kbps...
 tc class add dev eth0 parent 1:1 classid 1:10 htb rate...
 ...
 
 tc qdisc add dev eth1 root handle 1: htb default 13
 tc class add dev eth1 parent 1: classid 1:1 htb rate 100kbps...
 tc class add dev eth1 parent 1:1 classid 1:10 htb rate...
 ...

Is this valid? Or do I have to use "2:" instead of "1:" in the second
part?

thanx
cb
