Merge branch 'mlx5-next'

Saeed Mahameed says:

====================
Mellanox, mlx5 next updates 2018-08-09

This series includes mlx5 core driver updates and mostly simple
cleanups.

From Denis: Use max #EQs reported by firmware to request MSIX vectors.

From Eli: Trivial cleanups, unused arguments/functions and reduce
command polling interval when command interface is in polling mode.

From Eran: Rename vport state enums, to better reflect their actual
usage.
