I agree that the node type enum isn't particularly useful and should be
retired. In fact, I don't see where RDMA_NODE_IB_SWITCH is used by any
upstream device. So I don't think there's any obligation to keep it. But even
if we do, I'm not sure this is the correct approach. I don't know this for a
fact, but it seems more likely that someone would embed Linux on an IB switch
than they would plug an IB switch into a Linux based system. The code is
designed around the latter. Making this a system wide setting might simplify
the code and optimize the code paths.
