I understand why you use the internal DPDK version. 
However, I am hopeful (for the future) that cross-collaboration with the DPDK
project can avoid the need of keep doing this (for all the good reason of having
a common up-stream project with all the goodies in it rather than some sort of
"fork" in a consumer project).

We support DPDK since version 2.2 (roughly mid-2015) so I would say any
processor which is not older than 2 years...

I think the easiest for me here is to post here the link to our .spec file used
to generate the package we ship...
https://build.opensuse.org/package/view_file/network/dpdk/dpdk.spec?expand=1
You should be able to access it; in case you can't, please, let me know so I can
send it to you...

I'm going to try your suggested steps and will let you know how it goes.
