To talk about solution, someone needs actually to convince that the
problem exists and right now we are talking about change in internal
implementation of pretty well explained feature - provide device list.

I don't see any API or utils in the rdma-core which promised to provide
sorted output.

The manual is not enough, what about other tools? Should we update them
too? Or do we need to make ibstat special while rest of the tools keep
the list unsorted?

Maybe I'm part of the problem, but any solution will require unified
approach for whole rdma-core, so users like you will get stable and
consistent result from any rdma-core API/tool.
