Perhaps of interest:

Replacing the filter line with:
tc filter add dev $DEV protocol ip parent 1: prio 2 u32 match u8 0 0x0 at 0 flowid 1:1
tc filter add dev $DEV protocol ip parent 1:1 prio 2 u32 match u8 0 0x0 at 0 flowid 2:
will convince the packet to trickle down to 2:.
Adding
tc filter add dev $DEV protocol ip parent 2: prio 2 u32 match u8 0 0x0 at 0 flowid 3:
will not get it down to 3: however.
Also, adding just
tc filter add dev $DEV protocol ip parent 1: prio 2 u32 match u8 0 0x0 at 0 flowid 2:

will _not_ get it down to 2:.

I think this has gotten to the point where kernel versions are
interesting, I'm running 2.4.21-pre5-ac3.
