net-next was closed at this time, so I sent it with RFC during that 
window to get any feedback to make needed changes before it opened again.

There are a couple of patches for net that will cause merge conflicts 
with this so I'm trying to get those in before submitting the non-RFC 
version of this to minimize conflicts. I'm hoping to submit this next week.

Thanks,
Tony
