Merge branch 'mlx4-misc-patches' 



Tariq Toukan says:

====================
mlx4 misc patches

This patchset contains misc patches from the team
to the mlx4 Core and Eth drivers.

Patch 1 by Eran replaces large static allocations by dynamic ones.
Patch 2 by Leon makes an explicit conversion and solves a smatch warning.
In patch 3 I fix a misplaced brackets of the sizeof operation.
Patch 4 by Moshe adds the ability to inform the FW regarding user mac updates.

Series generated against net-next commit:
901c5d2f ARM: dts: rk3228-evb: Fix the compiling error
====================
