Status of the RDMA code

[Ivanov, Vladimir A]

Hi,
we finished with patch for the RDMA: JEP https://openjdk.java.net/jeps/337; Enhancement https://bugs.openjdk.java.net/browse/JDK-8195160

The webrev against default HEAD for this patch available as http://cr.openjdk.java.net/~sviswanathan/Vladimir/RDMA/webrev.00/

For latest binaries and configuration all JDK tests for the rsockets passed for 1000 iterations.
The tests run results for one iteration looks as:
