Aharon Landau says: ==================== 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. ==================== * mlx5_realtime_ts: RDMA/mlx5: Support real-time timestamp directly from the device RDMA/mlx5: Refactor get_ts_format functions to simplify code Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
