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.
