Chris Wright 51798a5d1c node_device: udev driver does not handle SR-IOV devices 
The udev driver does not update a PCI device with its SR-IOV capabilities,
when applicable, the way the hal driver does.  As a result, dumping the
device's XML will not include the relevant physical or virtual function
information.

With this patch, the XML is correct:

# virsh nodedev-dumpxml pci_0000_09_00_0
<device>
  <name>pci_0000_09_00_0</name>
  <parent>pci_0000_00_1c_0</parent>
  <driver>
    <name>vxge</name>
  </driver>
  <capability type='pci'>
    <domain>0</domain>
    <bus>9</bus>
    <slot>0</slot>
    <function>0</function>
    <product id='0x5833'>X3100 Series 10 Gigabit Ethernet PCIe</product>
    <vendor id='0x17d5'>Neterion Inc.</vendor>
    <capability type='virt_functions'>
      <address domain='0x0000' bus='0x0a' slot='0x00' function='0x1'/>
      <address domain='0x0000' bus='0x0a' slot='0x00' function='0x2'/>
      <address domain='0x0000' bus='0x0a' slot='0x00' function='0x3'/>
    </capability>
  </capability>
</device>

# virsh nodedev-dumpxml pci_0000_0a_00_1
<device>
  <name>pci_0000_0a_00_1</name>
  <parent>pci_0000_00_1c_0</parent>
  <driver>

  </driver>

    <capability type='phys_function'>
      <address domain='0x0000' bus='0x09' slot='0x00' function='0x0'/>
    </capability>
  </capability>
</device>
