Merge branch 'mlx4'
Or Gerlitz says:
====================
Here's a batch of fixes to the mlx4 core and ethernet drivers for 3.9
The commit that disabled RFS when running in SRIOV mode fixes a regression which was
introduced in 3.9-rc1 but actually present also in the 3.8 -stable series. It turns out
that a slightly different fix is needed there and we will generate and submit it there.
Patches done against net commit 66d29cbc59433 "benet: Wait f/w POST until timeout"
====================
