Merge branch 'mlx5-next' 

Eli Cohen says:

====================
mlx5 update for 3.18

This series integrates a new mechanism for populating and extracting field values
used in the driver/firmware interaction around command mailboxes.

Changes from V1:
 - Remove unused definition of memcpy_cpu_to_be32()
 - Remove definitions of non_existent_*() and use BUILD_BUG_ON() instead.
 - Added a patch one line patch to add support for ConnectX-4 devices.

Changes from V0:
 - trimmed the auto-generated file to a minimum, as required by the reviewers.
