I didn't get your question. The only information exchanged between the stages is mbuf pointer. So the information has to be in mbuf, whether it's part of Meta or in private area in the packet buffer headroom is that the question you are asking. The private area is application specific, while I am looking for the port information getting updated from driver to application and it's generic to multiple applications. 

Regards
Kannan Babu

Have you tried to move this field outside of the mbuf?
What is the performance degradation?
We need more information than some assumptions.
