IP ToS only works on Windows XP/2003 #5

Figure out why setting the IP ToS works on Windows XP/2003 but not on Windows 
Vista/7.  (At least in my testing)

Windows XP/2003 requires you to add a registry setting to enable it, does 
Vista/7 have something similar you have to change?

Or, is the code wrong?  =/

Looks like it's deprecated in Vista/7 and setting the socket option takes no 
effect: http://blogs.msdn.com/b/wndp/archive/2006/07/05/657196.aspx

We can set the ToS (DSCP) field on vista/7/server 2008 using the QOS2 API, and 
namely QOSSetFlow:
