Code review: 7079012 test/java/net/NetworkInterface/NetParamsTest.java fails with SocketException getting mac address

[Michael McMahon]

Could I get the following webrev reviewed please?

http://cr.openjdk.java.net/~michaelm/7079012/webrev.1/

We're getting an unexpected error in native code on Solaris when calling
the ioctl() that returns hardware MAC addresses for certain kinds of 
NetworkInterface.
So, the fix is not to throw an exception, but to return a null byte[] 
instead.

The fix also adds support for the new Solaris 11 SIOCGLIFHWADDR ioctl()

Thanks,
Michael.
