Giving this more thought, I think there are at least two separate issues.  One 
is defining what backlog means from the perspective of the rdma_listen() API. 
The userspace and kernel APIs don't doesn't necessarily need to have the same 
definition.

The second issue that I see is mapping backlog to underlying CMs.  A single 
rdma_listen call can result in separate listen calls to underlying devices. 
(Obviously, a simple mapping is to just pass the value down.)
