[dpdk-users] Why packet_type is zero?

Hello,

I have the following setup of VirtualBox machines on a single host:
node2:
  eth0: VBox NAT, connecting to the host internet
  eth1: 192.168.1.12/24
   and additional route for 192.168.0.0/16 -> gateway 192.168.1.11

dpdk-node:
  eth0: VBox NaT, connecting to the host internet
  eth1: 192.168.1.11/24
  eth2: 192.168.2.11/24

Now I run
     node2 $ ping 192.168.2.13
so, following the route, it sends the ping ICMP messages to 192.168.1.11 
(dpdk-node).

On the dpdk-node I run l3fwd:
     dpdk-node $ sudo examples/l3fwd/build/app/l3fwd -c 0x01 -n 2 -- -p 
0x03 --config="(0,0,0),(1,0,0)"
with APP_LOOKUP_METHOD = APP_LOOKUP_EXACT_MATCH, and with some 
debug-printfs. In particular I printf
m->packet_type in the beginning of the l3fwd_simple_forward function.

Question:
Why does it prints 0? What is a possible causes?

P.S. my DPDK version is 2.1.0; The printf is executed on each ping 
message; tcpdump shows no other traffic in this internal network.

Respectfully,
Arseniy.
