DPDK minimal version

[tarelda]

What is maximal and minimal DPDK version for packetjourney to compile?

[fatih-acar]

Packet-journey should compile using DPDK versions from 1.8 up to 18.08.
I've pushed commit 35cceb7 which adds support for 18.08.

I started with 2.0 and found success starting with 18.02. My approach consisted of trying to find the first commit fixing thing that compiler was complaining about and then picking up the first stable version that implemented it.

@fatih-acar I just realised that my repository was lagging one commit behind current master. So I fast forwarded it to HEAD and tried to compile pktj against DPDK 18.08.1 and suprisingly it didn't work.

What is more, I tried to compile this codebase against previously working 18.02 and it also failed.
