I'm prototyping a server that needs to accept a large number of

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.
