Subject: [SR-IOV driver example 3/3] VF driver tar ball

The attachment is the VF driver for Intel 82576 NIC. Since the VF
appears as the normal PCI device driver, this VF driver has no
difference from other PCI NIC drivers. It handles interrupt, DMA
operations, etc. to perform packet receiving and transmission.

How the design of the VF internals is up to the hardware vendor.
So the VF may have totally different register set from the PF,
which means the VF driver may have its own logics (rather than
derive from PF driver) to handle the hardware specific stuff.
