I'm having troubles with TC policing, the ingress filters does not seem to be

I observed similar behavior when configuring a filter on ingress qdisc.
Test shows that traffic was rate-limited to the configured value. 
However, "tc filter show" does not show any filtering rule.

(1) add ingress qdisc on eth1
# tc qdisc add dev eth1 ingress
# tc qdisc show dev eth1 ingress
qdisc pfifo_fast 0: root refcnt 2 bands 3 priomap \
 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1
qdisc ingress ffff: parent ffff:fff1 ---------------- 

(2) add filter under ingress qdisc
# tc filter add dev eth1 parent ffff: protocol all \
 u32 match ip src 0.0.0.0/0 \
 police rate 256kbit burst 10k drop flowid :1
# tc filter show dev eth1

(3) verified sch_ingress kernel module is installed
# lsmod  | grep sch_ingress
sch_ingress            12866  1

(4) uname -a (if needed for debugging)
Linux huan-lnx 3.16.0-30-generic #40~14.04.1-Ubuntu SMP

I am testing this using ubuntu 14.04 on a virtualbox VM
(eth1 is a host-only adapter).

Thanks,
Huan
