[dpdk-dev] Need help on dpdk packet-generator

[Mahesh Ishwar Mathad]

Hi team,

Kernel Version :  4.5
DPDK Version :    16.07.2
PKT-GEN Version:  3.3.4


I am trying to execute dpdk pkt-gen application to generator L2 traffic 
on DPDK ports. But I am getting errors while executing command :
./app/pktgen -c 0x7 -n 3 -- -p 0x1 -P -m "[1:2].0"

Since I am allocating enough huge page ie 2048Kbytes and i tried with 
4096Kbytes also and I bind DPDK ports to igb_uio driver but still i am 
getting below error:
