Code Review 6972374: NetworkInterface.getNetworkInterfaces throws "java.net.SocketException" on Solaris zone

[Chris Hegarty]

Dmitry, Alan,

The Solaris version of getFlags sets an Exception if the ioctl fails. 
When used in addif getFlags will fail when access to the virtual 
interface's parent is forbidden, i.e. in a zone. addif is called when 
iterating over interfaces in enumIPvXInterfaces, if an exception occurs 
it simply cleans up and returns, propagating the exception.

getFalgs should not set an exception. All other calls to it check the 
return value and set an exception if appropriate.
