Re: [dpdk-users] Why packet_type is zero?

[Arseniy Zaostrovnykh <arseniy.zaostrovnykh@epfl.ch>]

Forgot to mention:
I tried KNI (first detaching eth1 and eth2 from the kernel) and pcap PMD 
drivers, with:
     dpdk-node $ sudo examples/l3fwd/build/app/l3fwd -c 0x01 -n 2 
--vdev=eth_pcap0,iface=eth2 --vdev=eth_pcap1,iface=eth1 -p 0x03 
--config="(0,0,0),(1,0,0)"
The sysptoms are identical.
