NAME
     PCI_IOV_UNINIT — disable SR-IOV on a PF device


SYNOPSIS
     #include <sys/bus.h>
     #include <dev/pci/pci_iov.h>

     void
     PCI_IOV_UNINIT(device_t dev);


DESCRIPTION
     The PCI_IOV_UNINIT() method is called by the PCI Single-Root I/O Virtualization (SR-IOV) infrastructure
     when the user requests that SR-IOV be disabled on a Physical Function (PF).  When this method is called,
     the PF driver must release any SR-IOV-related resources that it has allocated and disable any device-
     specific SR-IOV configuration in the device.

     This method will only be called following a successful call to PCI_IOV_INIT(9).  It is not guaranteed that
     PCI_IOV_ADD_VF(9) will have been called for any Virtual Function (VF) after the call to PCI_IOV_INIT(9) and
     before the call to PCI_IOV_UNINIT.
