QOS with TC and multiple LAN devices

Hi,

I have got a question about setting up QOS with TC.

I have several examples and HowTo's how to setup QOS with a single local LAN
device (e.g. eth0).
My question now is how to setup the rules/roots if I want to use 2 (or more)
LAN devices (eth0/eth1).

In simple:

ppp0 as DSL WAN interface
eth0 (192.168.0.0/24), eth1 (192.168.1.1/24) as LAN interfaces

As simple example the following rules would help me:
routing eth0<->eth1 without limit
routing eth0<->ppp0 always higher priority than eth1<->ppp0
ACK on eth0<->ppp0 higher priority than rest on eth0<->ppp0
VNC/ACK on eth1<->ppp0 higher priority than rest on eth1<->ppp0


At the end want to extend the fli4l QOS opt for multiple devices, but first
I need to understand how to setup TC for multiple LAN devices and therefor I
need your help.


Thank you.
