Subject: [PATCH 00/25] mlx4: multi-function framework and Ethernet sriov.

In ConnectX, nearly all device resources can be associated with any function.
Once allocated, these resources can be manipulated exclusively by their associated
functions in the same manner as in the single-function case.

The device continues to use a single HCA Command Register (HCR), which is owned by the pf.
Thus, the pf is given the role of allocating resources to vfs, and controlling shared
resource (such as ports).

A dedicated HW communication channel is used to transfer resource allocation and
modification requests from vfs to the pf, and events from the pf to the vfs.
Consequently, no hypervisor-specific services are required for pf-vf communication.

This patch set sets the ground for multi-function operation and enables Ethernet interfaces on vfs.
