We may need to specify which commit (or branch, tag) we can apply the patch to the QDMA DPDK repo.

From the timeline of two repos, this commit works for me.

Yep, we can find the commit based on the time of this repo. QDMA DPDK driver updated after the last commit of this repo. We may need to add commit ID in the readme to tell the user which commit should be used.

Thanks, I updated the README instructions towards checking out the commit #7859957 of the dma_ip_drivers based on the above suggestions.
