Dear all,
I have a linux box with two NICs: eth0 (10 Mbit) and pvc0 (64Kbit) (pvc over
frame-relay with a WAN card).
I have two kinds of traffic incoming on eth0: Best effort traffic (TOS=0)
and VoIP traffic (TOS=5).
I want to simply configure the linux box so that It priorizes the VoIP
packets so that all VoIP packets are sent before transmitting the BE
packets. Which command I need with tc?
Looking at LARTC Howto It seems that I can match only packets with TOS 2,4,8
and 16... I didn't understand very well that part...
Luca Andreani

TOS is just 8 byte, so I think you can do this :
u32 match ip tos 0x05 0xff

oops, 8 bits ....
