Hi Alex,

The hardware isn't public yet, so can't talk about it :-(. Once this patch gets
merged, will let the OSV engagement folks drive it for inclusions. We
could mark this for stable, but i would rather wait until we know the
timeline when they are expecting it to be in. It shouldn't break anything
since we are just enforcing the spec.

Cheers,
Ashok
