Updated patch to not discard UDPv6

Hi Franco,

Thanks for the review. I believe the team from Microsoft is reviewing the patch
right now since they emailed me about the bitwise &.

It was actually a typo which I have fixed in this patch. Functionally the &
worked but switching to && should be faster since && can "short-circuit".
