From Michael,

The series adds support for on-demand paging for DC transport.
Adding handling of DC WQE parsing upon page faults and exposing
capabilities.

As DC is mlx-only transport, the capabilities are exposed to the user
using the direct-verbs mechanism. Namely through the
mlx5dv_query_device.

Thanks

Thanks

  IB/mlx5: Expose ODP for DC capabilities to user
  IB/mlx5: Add page fault handler for DC initiator WQE
