David, Stephen,

The kernel code is accepted to the RDMA and will be sent to Linus in this merge window, and this is refreshed version of user space part.

Because, I found bug in handling cxgb4 devices and we cleaned header file a little bit more, it was more wise to resend the series instead of applying v2.
