[dpdk-users] generate ipv6 packets with pktgen

Hi all,

I need to generate IPv6 packets with pktgen, but I am NOT able to set 
the IPv6 src and dst address

when I only change the packet type of port 0 to IPv6

Pktgen:/> set 0 type ipv6
Pktgen:/> start 0

pktgen sends IPv6 packets with meaningless IPv6 addresses
here is the tcpdump output:
18:23:37.777126 IP6 ::101:a8c0:0:0.0 > ::101:a8c0:0:0.0: Flags [.], ack 
1, win 8192, length 0

but if I try to set the src and dst addresses:

Pktgen:/> set 0 dst ip 2000::1
Pktgen:/> set 0 src ip 2000::2/64

the IP (v4) addresses in the main page display are zeroed:
Dst  IP Address   :             0.0.0.0
Src  IP Address   :             0.0.0.0

and when I ask to generate packets
Pktgen:/> start 0

pktgen sends IPv6 packets with "zeroed" addresses
18:48:42.475672 IP6 ::.0 > ::.0: Flags [.], ack 1, win 8192, length 0

is it possible to set the IPv6 addresses?

thank you
Stefano
