FYI, I also really hate the idea of having to potentially allocate
resources on each device at driver load time which the client registration
forces us into.
I really think we need to take a step back and offer interfaces that don't
suck in the core instead of trying to work around RDMA/CM in the core.
Unfortunately I don't really know what it takes for that yet. I'm pretty
busy this work, but I'd be happy to reserve a lot of time next week to
dig into it unless someone beats me.
I suspect a big part of that is having a queue state machine in the core,
and getting rid of that horrible RDMA/CM event multiplexer.
