Merge branch 'mlx5_realtime_ts' into rdma.git for-next
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
