Artemy Kovalyov 1a2fdf1c53 IB/mlx5: Compare only index part of a memory window rkey ...

[ Upstream commit d623dfd283 ]

The InfiniBand Architecture Specification section 10.6.7.2.4 TYPE 2 MEMORY
WINDOWS says that if the CI supports the Base Memory Management Extensions
defined in this specification, the R_Key format for a Type 2 Memory Window
must consist of:

* 24 bit index in the most significant bits of the R_Key, which is owned
  by the CI, and
* 8 bit key in the least significant bits of the R_Key, which is owned by
  the Consumer.

This means that the kernel should compare only the index part of a R_Key
to determine equality with another R_Key.
