Or Gerlitz says:

====================
mlx4: Add support for single port VFs

The mlx4 Firmware && driver expose both ports of the device through one PCI function.

This can be non-optimal under virtualization schemes where the admin
would like the VF to expose one interface to the VM, etc.

This series from Matan Barak adds support for single ported VFs.

Since all the VF interaction with the firmware passes through the PF
 driver, we can emulate to the VF they have one port, and further create
a set of the VFs which act on port1 of the device and another set which
acts on port2.

Series done against net-next commit 3ab428a "netfilter: Add missing
vmalloc.h include to nft_hash.c"

Roland, we send this through netdev, but if you have comments, will love
to hear them.
