Merge branch 'mlx5-connectx-4-sriov' 

Or Gerlitz says:

====================
Introducing ConnectX-4 Ethernet SRIOV

This patchset introduces the support of Ethernet SRIOV in ConnectX-4
family of 100G Ethernet NICs.

Some features are still missing, but all the basic SRIOV functionalities
are there already.

Basic Introduction:
ConnectX-4 HW architecture provides two kinds of underlying HW switches.

MPFS (Multi Physical Function Switch) or L2 Table in Software terms:

The HCA has one MPFS switch per physical port, this switch is responsible
of forwarding Unicast traffic to the various overlying Physical Functions (PFs).
Multicast traffic is flooded amongst all the PFs, Each PF can request to
forward a unicast MAC to its E-Switch Uplink vport (which we will cover later)
through SET_L2_TABLE_ENTRY HW command.

MPFS has five ports, four are connected to PFs (one for each) and one is connected
directly to the Physical Port (Physical Link).

E-Switch (Ethernet Switch):

The HCA has one per physical function. The main responsibility of this component is
to forward Unicast/Multicast and vlan tagged/untagged traffic to the various
Virtual Functions (VFs) allocated by the PF. Unlike MPFS, the PF needs to explicitly
create the E-Switch FDB table, Which is a HW flow table managed by the PF driver
whenever vport_group_manager capability bit is set for this PF.

E-Switch has Virtual Ports (vports) entities as its ports, vport0 and uplink vport
are special kind of vports that represents PF vport (vport0) and uplink vport which
is connected to the MPFS switch (if exists) as the PF external link.
vport1..vportN represent VF0..VF(N-1) egress/ingress ports.

E-Switch FDB contains forwarding rules such as:
        UC MAC0 -> vport0(PF).
        UC MAC1 -> vport1.
        UC MAC2 -> vport2.
        MC MACX -> vport0, vport2, Uplink.
        MC MACY -> vport1, Uplink.

    For unmatched traffic FDB has the following default rules:
        Unmatched Traffic (src vport != Uplink) -> Uplink.
        Unmatched Traffic (src vport == Uplink) -> vport0(PF).

NIC VPort context:
Each NIC (VF/PF) has its own vport context which will be used to store the current
NIC vport context (UC/MC and vlan lists) and other NIC properties such as MTU, promisc
mode, etc.. NIC (VF/PF) driver is responsible of constantly updating this context.

FDB rules population:
Each NIC vport (VF/PF) will notify E-Switch manager of its UC/MC vport
context changes via modify vport context command, which will be
translated to an event that will be handled by E-Switch manager (PF)
which will update FDB table accordingly.

Both PF and VF use the same driver and submit commands directly to the firmware.
The PF sees the vport_group_manager capability bit and as such runs the code
to populate the embedded switches as explained above.

The patch goes as follows:

Patches 1-2 introduces the basic PCI SRIOV functionalities and the support of
Connectx4 to enable specific VFs via enable/disable HCA commands. These two
patches will be also in use later for the IB SRIOV flow.

Patches 3-8 Introduces the basic E-Switch capabilities and commands to be used later by
VF to modify and update its NIC vport context, and by PF (E-Switch Manager) driver to
Query the VF NIC context and acts accordingly.

Patches 9-10 Provide the needed functionality of a NIC driver VF/PF to support SRIOV,
mainly vport context update support.

Patch 11 ("net/mlx5: Introducing E-Switch and l2 table"), Introduces the basic
E-Switch support and infrastructure to read vport context events and to update
MPFS L2 Table of the UC mac addresses request by the PF.

Patches 12-18 Introduces SRIOV enablemenet and E-Switch FDB table management
It adds the Basic E-Swtich public API to set and get sriov properties to be used
in PF netdev sriov ndos.

Patchset was applied ontop of commit 3f8c0f7e "gianfar: use of_property_read_bool()"

Saeed, Eli and Or.

changes from V0, addressed feedback from Alex Duyck:
 - patch 09, remove the loop to seek the device address

 - patch 10, fix possible buffer over-run

changes from V1, addressed feedback from and Julia Lawall and kbuild test robot
 - patch 11 check the right variable for allocation failure
 - patch 18 eliminated unneeded semicolon
