 buffer to write in total ring size percentage

Maybe best through greg's char-misc tree since it has generic hv code and sometime updates both network and scsi.

Alternatively,  put common code through one tree, and hold off the network device change till next release.

Martin,

I hope this patch set goes through SCSI, because it's purpose is to improve storvsc.

If this strategy is not possible, I can resubmit the 1st two patches to net, and the 3rd patch to scsi after the 1st two are merged.
