Use 2 filters :
1. all z.x.y to a class
2. all to an other class
so the second filter matches all except x.y.z

It's not possible. The ingress qdisc is not a real qdisc. All egress qdiscs
like htb/cbq/sfq are changing the queue of packets that leaves a nic. But
for incoming there is no queue that you can change.
So you can add a ingress qdisc and you can use filters+policers to manage
incoming traffic, but it will not so powerfull as you can with outgoing
packets. You can't delay a packet with the ingress qdisc.
