Hi Thomas & David,

We haven't got the final status on this patch, and I don't see this change even from the latest LTS 20.04 repo.
So I'd like to confirm whether this patch has been safely submitted to the main upstream.
Can you check the status of that commit?

Thanks for your support in advance,
Keesang

This patch was merged in 20.02.
We don't have any feedback about issues so it's probably working fine.

It is solving a problem for running DPDK on machines having a lot of cores.
Now the difficult question: is it a new feature or a fix?
Should we backport this patchset?
