 * Fixed reserved_* field wrong name (Saeed M.)

---------------------------------------------------------------------------------
From Michael,

The series adds support for on-demand paging for DC transport.

As DC is mlx-only transport, the capabilities are exposed
to the user using DEVX objects and later on through mlx5dv_query_device.

Thanks

  IB/mlx5: Remove check of FW capabilities in ODP page fault handling
  IB/mlx5: Add page fault handler for DC initiator WQE

This seems fine, can you put the commit on the shared branch?
