Merge branch 'mlx4'

Or Gerlitz says:

====================
This series adds support for the SRIOV ndo_set_vf callbacks to the mlx4 driver.

Series done against the net-next tree as of commit 37fe0660981d7a "net:
fix address check in rtnl_fdb_del"

We have successfully tested the series on net-next, except for getting
the VF link info issue I have reported earlier today on netdev, we
see the problem for both ixgbe and mlx4 VFs. Just to make sure get
VF config is working OK with patch #6 - we have run it over 3.8.8 too.

We added to the V1 series two patches that disable HW timestamping
when running over a VF, as this isn't supported yet.
====================
