Leonid Arsh has a patch that I will integrate soon that makes this
configurable.
However, I'm curious. Do you have a workload where this actually
makes a measurable difference? It seems that having 4 RDMA requests
outstanding on the wire should be enough to get things to pipeline
pretty well.
If you haven't tested this, right now you can of course edit
mthca_main.c to change the default value and recompile.
