This argument can be repeated multiple times. Its main use is to allow network interfaces be created
as ``enoX`` on Linux, with X being the instance number, instead of the name depending on the interface
position on the PCI bus.
Here is an example of use:
.. parsed-literal::
-netdev user,id=internet \\
-device virtio-net-pci,mac=50:54:00:00:00:42,netdev=internet,id=internet-dev \\
-smbios type=41,designation='Onboard LAN',instance=1,kind=ethernet,pcidev=internet-dev
In the guest OS, the device should then appear as ``eno1``:
..parsed-literal::
$ ip -brief l
lo UNKNOWN 00:00:00:00:00:00 <LOOPBACK,UP,LOWER_UP>
eno1 UP 50:54:00:00:00:42 <BROADCAST,MULTICAST,UP,LOWER_UP>
Currently, the PCI device has to be attached to the root bus.
