[openfabrics-ewg] Cisco SQA results so far for OFED 1.0 rc5

[Tziporet Koren]

Note that rdma_lat is the oldest test that was written.
We wrote a new set of performance tests that are maintained:

Latency tests:
write_lat - RDMA write
read_lat  - RDMA read  
send_lat  - Send (ud & rc)

Bandwidth test:
write_bw - RDMA write
read_bw  - RDMA read
send_bw  - Send (ud & rc)


All these tests are installed under <prefix>/bin. You can run them with
-h to get the usage.

Great!  We were also able to reproduce the problem using rdma_lat.

We've added rdma_lat to our smoke test, so we detect this kind of
problem sooner.
