How do you do it in userspace?  With a bind()?  That is a little
wasteful in that you are reserving a local addr/port when all you really
need to reserve is the actual local/remote 4-tuple that you are going to
use for the connection, but that's not horrible.

Actually cma.c still has the problem of host/offload port space collisions.

The whole port sharing thing is a mess -- I was hoping you had come up
with a good solution that cma.c could steal to be honest, so I don't
have any better ideas at the moment.
