Excellent patch and works like a charm on the U300. My loopback code
would generate
spurious overfill errors before and now it *never* fails so you hit
exactly the right spot.
I remember being intrigued by this when I worked on the driver and now

As some sort of maintainer of this file I have signed it off and put
it into Russells
patch tracker for inclusion, OK? See;
