Saeed Mahameed says:

====================
mlx5-update-2017-05-23

First patch from Leon, came to remove the redundant usage of mlx5_vzalloc,
and directly use kvzalloc across all mlx5 drivers.

2nd patch from Noa, adds new device IDs into the supported devices list.

3rd and 4th patches from Ilan are adding the basic infrastructure and
support for Mellanox's mlx5 FPGA.

Last two patches from Tariq came to modify the outdated driver version
reported in ethtool and in mlx5_ib to more reflect the current driver state
and remove the redundant date string reported in the version.
