Thanks,

I am going to apply this. But as noted in residue patch I think the restriction
of single descriptor is an artficial one and we cna do better in SW. This also
bring the abuse the completion status to track the channel status which shouldnt
be required/gone once we do multiple descriptors. But those should be handled
as another patch series!
