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:

Means you have to allocate hugepages before starting this app.

You should be able to find more information about setting up Pktgen in the docs.
http://pktgen-dpdk.readthedocs.io/en/latest/

If you have not attached ports to the igb_uio module, please look at the usertools/dpdk-devbind.py usage.
