If you don't test the DPDK in virtualization environment.
The easy way to fix it is to disable the VT-d in the BIOS.

Hi Anatoly

It seems that the problem was Ubuntu distribution.
We switched to Ubuntu 14.04 Server Edition and sending packets through NIC works like charm

Thanks
Tomasz

PS.
This is for google to index in case anyone else has similar problems If You are using:
HP ProLiant DL380p Gen8
HP SmartArray p420
Intel 82599EB

Use Ubuntu 14.04 as Your host OS !!!
