Re: rdma_listen() backlog maximum

I'm prototyping a server that needs to accept a large number of
simultaneous incoming RDMA CM connections. I noticed that
drivers/infiniband/core/ucma.c limits the backlog to 128. Is there a
reason why the limit is 128? Or to put it another way, what breaks if
the limit is increased to a larger value (say 256)?

My understanding is that with the current cma/cm code, under IB/IBoE
the backlog has no impact, in that environment, you're practically 
limited by the mad layer ability to receive the REQ mads. Sean, am I 
correct?

Or.
