Hi DPDK maintainer,
We want to upstream our dpdk patch for fixing bug. But it seems that "git send-email" still can't be work. Can you review and apply this patch to branch 20.11 of git repository dpdk_stable.

I assume you added the patch as an attachment - that will not work,
attachments are not allowed on this mailing list. There was no patch in
