Going in circles. I have said from the beginning of network namespace
support for rxe do not open the port until first rxe device create and
once opened leave it open. Simple design that limits socket churn to
users wanting to leverage rxe in a network namespace. Zhu Yanjun, if you
are going to be a maintainer of a feature you need to have a consistent
stance on the architecture and code design.
