Hi, David

Thank you for your feedback and for pushing this forward.

I completely agree that "ready-to-merge patches" are what drive the 
kernel forward. To that end, I have just finished rebasing and updating 
my implementation from 6.14 to the current 6.19-rc (and it’s ready for 
7.0-next).

I have full respect for your long-standing work on this. Since we both 
have functional solutions now, I suggest we quickly compare the design.

My goal is the same as yours: to finally get netns support into rxe for 
7.0. I will post my updated patch set shortly so the maintainers can 
evaluate both.

The patch link is: https://github.com/zhuyj/linux/tree/6.19-net-namespace

Please code review.

Best regards,
Zhu Yanjun
