Hi Ferruh,

That patch applied and worked (kind of):

---
[root at centos6-1 dpdk-16.04]# patch -p1 < ../dpdk-centos6.patch
patching file lib/librte_eal/linuxapp/igb_uio/compat.h
Hunk #1 succeeded at 24 with fuzz 2.
---

 It passed that broken step, however, it is failing in a different part of
build process now, as follows:

---
[root at centos6-1 ~]# time rpmbuild --ba /root/rpmbuild/SPECS/dpdk.spec

Might be a totally different problem now, I don't know...   :-)
