This is all useful and I'd like to move this forward. But the amount
of patches and lines in each patch is a bit too much to review
properly.
Can you try to split them a bit? I had a look in the first few patches
and sent some comments.
Perhaps you can send the PXE ones first even with the limitations of a
single device? And then send the multiple device support? Or the other
way around?

Thanks
