I think this has turned out really well now.  I've gone through the patches
today and not found any real show-stoppers, but replied with a couple of
minor things I noticed.

I think it's probably worth rearranging the rx and tx code to avoid
the spinlocks, which would be the main optimization I can still
think of to reduce the coherency traffic.
