Well, I am, I don't know what you are talking about.

Who cares?

Mellanox has been pushing dpdk centric HW features that no other
vendor has an interest in. So it is understandable there is not much
activity.

However this is an all-vendor software only feature that all HW can
support right now today, it is fundamentally different than the prior
HW entangled patches.

Consider the kAPI work to add the new MR stuff that Christoph
did. That would have been a total disaster if they didn't update all
the drivers to work with it at the same time.

Userspace is no different, and the responsibility falls with the patch
author to oversee that process and get it done before merging.
