Hi All

Is the filter rule bellow supposed to classify icmp request/reply packets?

 $TC filter add dev eth2 protocol ip \
    parent 1:0 prio 1 u32 \
    match ip dst 192.168.0.1 \
    match icmp type 8 0xff flowid 100
 $TC filter add dev eth2 protocol ip \
    parent 1:0 prio 1 u32 \
    match ip dst 192.168.0.1 \
    match icmp type 0 0xff flowid 100

it is accepted by tc but I think it is not filtering anything. icmp
packets are going thru default htb class.

How do I "see" if these rules are catching anything? Is there something
like the -s class option?

Any clues?
