Amir Vadai says:

====================
net/mlx4: Mellanox driver update 15-10-2013

This patchset contains small code cleaning patches, and a patch to make
mlx4_core use module_request() in order to load the relevant link layer module
(mlx4_en or mlx4_ib) according to the port type.
====================
