The solution to LU-3322 has made changes to how we can configure map_on_demand and peer_credits for o2iblnd-based connections. In that ticket, Jeremy has outlined some good information which should be captured in our documentation to help users better understand how to work with three tuning parameters: map_on_demand, peer_credits, and concurrent_sends.

We should also be documenting what good pre-sets to use for different node types: MDS/OSS, LNet routers, and clients.
