That would be great, anything you post I'll pull in immediately and test 
on real hardware in one of our ipv6 only clusters to make sure it's 
still working.  From my perspective none of your code has given me any 
problems, it pulls the dhcp information that uefi has already properly, 
and manually doing the bootp thing also works properly.  Thanks,
