Description
This test case verifies that the interface names for adapters on Add-in PCI slots are of the form pci<slot>#<port>_<virtual function instance>.
Setup
Make sure your system is booted into Rawhide kernel and has at least one add-in network controller plugged into the available PCI slot.
Howto Test
1. Identify the add-in network adapters in your system. Use instructions from the link 'https://fedoraproject.org/wiki/QA:Testcase_Onboard_Network_Interface_Names' to identify the onboard network devices. The rest are add-in network adapters.
On a PowerEdge with 4 BCM5709 onboard network adapters, 1 82572EI single port adapter, 1 82576 dual port network adapter, 'lspci' listing helps identify add-in adapters.

2. Verify that the add-in network adapters are named as per their physical location on the system board.
