Hi Stefan, thanks for asking. I kind of went astray from further pushing siw for mainline integration. That time I did all the suggested changes, and some more work went into it. I updated gitorious.org/softiwarp accordingly, but did not send again to the list. It might be a good idea to start another attempt.
I also saw SoftRoCE aiming for mainline integration. Don't know exactly their status, I guess it's about the same. We are happily using siw, I have it at gitorious.org/softiwarp, where I maintain it - loosely. I agree that a software based RDMA stack can be very useful. That's why I did that work.
