[dpdk-users] DPDK with 40G NICs

Hi,

I am trying to use DPDK with 40G NICs, starting with the pktgen application.

I have a machine with 6 dual-port Intel XL710 NICs and want to use 6 ports
at 40G (I think it's possible to use only one port in 40G fully saturated).

When I run pktgen, only one of the 40G NIC transmits packets (and it's the
last enabled NIC in the list). I launch pktgen as follows:

sudo ./app/app/x86_64-native-linuxapp-gcc/app/pktgen -c 0xffff -n 3 -- -P
-m
"[1:3].0,[2:4].1,[3:5].2,[4:6].3,[5:7].4,[6:8].5,[7:9].6,[8:10].7,[9:11].8,[10:12].9,[11:13].10,[12:14].11"

Everything seems to work normally, but typing start all, starts only the
last port. Starting with the portid also doesn't work.

Any suggestion?

Best regards,
Chris
