Merge branch 'mlx4-next'

Amir Vadai says:

====================
Mellanox driver update Jul-08-2014

This patch set introduce some small bug fixes.
Most of the patches are small fixes to cornet case bugs.
The patch by Noa ("Fix mac_hash database inconsistency") was sent in the past
[1] and was droped because a fix to the bonding code was supposed to make it
unnecessary. After a second look on the patch, it is still needed even
after the direct access to dev_addr by the bonding will be fixed.

Patches were applied and tested over commit bd4578b
("drivers/net/hyperv/netvsc.c: remove unnecessary null test before kfree")
