Code Review Request: 7127771: (macosx)test/java/net/Socket/TrafficClass.java fails on Mac OS X

[Kurchi Hazra]

Hi,

For IPv6 on solaris or linux, setting the traffic class option is 
handled in the java layer.
The native calls to set socket option simply returns a success and get 
socket option
returns a dummy -1 value. test/java/net/Socket/TrafficClass.java
was failing on Mac OS X when using the IPv6 stack with an Invalid 
Argument Socket
Exception since this native handling was missing when setting socket option.

The following change incorporates the required native behavior for Mac OS.
