Hi Doug,

This series adds memory re-registration support for the mlx5 driver.
Re-registration of memory region uses UMR if the current MKey is large
enough to encompass the requested length. When this is not possible,
a new MKey is created using the firmware command interface. In this
case, new LKey and RKey are created and must be communicated to
remote peers by the user.

The MR's umem is kept only through a PD-only change. Otherwise, it is
replaced as well.

The series contains 2 patches:
The first patch refactors the register and deregister MR flow so that
some code parts could be shared later on with the re-registration
flow.
The second patch introduces the actual re-registration flow.

Thanks,
Noa and Matan
