From: Leon Romanovsky <leonro@nvidia.com> In case device supports only real-time timestamp, the kernel will fail to create QP despite rdma-core requested such timestamp type. It is because device returns free-running timestamp, and the conversion from free-running to real-time is performed in the user space. This series fixes it, by returning real-time timestamp.
