You do realize that the code on openib.org is from multiple vendors,
right? I only touched one part of that code. That's why I said 'some'.

complete rewrite?

Sure it can. I replied to your email. Check the mail headers,
specifically the ones labeled References and In-Reply-To.

I didn't need an immediate answer.
