About this error, make sure you are using the kernel modules provided by the mlnx-ofed-kernel package from MOFED [1] as described in the documentation. In short, unload mlx4_core, mlx4_en, mlx4_ib and ib_uverbs, install this package, run depmod and load them again. Since they have similar names, the updated kernel modules should be found in a "extra" or "updates" subdirectory of /lib/modules and come first when queried by modinfo.
