Thomas,
I have replied to the other mail, here I just want to confirm, that I'm
fine with the proposed "general messaging" which other libraries (IF
Proxy including) could utilize.

Do you have also inter-lcore communication in mind here? Or just
"external" world to "some DPDK controller/dispatcher" and how that is
passed to other cores is an application writer problem.

Yes, lets talk about that.
