Subject: [PATCH rdma-next 0/2] Provide already supported real-time timestamp

From: Leon Romanovsky <leonro@...dia.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.

Thanks

  RDMA/mlx5: Support real-time timestamp directly from the device
