[openib-general] [PATCH] [RFC] - example user mode rdma ping/pongprogram using CMA

[Steve Wise]

Sounds like the connection didn't get setup...

By default it should run continually ping/ponging until you hit ctrl-c.
Without -d or -v, you won't see any output. If it exited, then something
must have failed.  -d should show more info.  The -vV flags will display
the ping/pong messages and validate the data.

I assume you can ping between the two systems over ipoib interfaces?
