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.


  • Onboard Network Adapters
[root@fedora-14-r710 ~]# lspci | grep -i ether
01:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
01:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
02:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
02:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
  • PCI Add-in Network Adapters
06:00.0 Ethernet controller: Intel Corporation 82572EI Gigabit Ethernet Controller (Copper) (rev 06)
07:00.0 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)
07:00.1 Ethernet controller: Intel Corporation 82576 Gigabit Network Connection (rev 01)

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

[root@fedora-14-r710 ~]# ls /sys/class/net/
em1  em2  em3  em4  lo  pci3#1  pci3#1_0  pci3#1_1  pci3#2  pci3#2_0  pci3#2_1  pci4#1


  • pci4#1 - add-in network adapter on PCI Slot 4 Port 1
[root@fedora-14-r710 ~]# ethtool -i pci4#1
driver: e1000e
version: 1.2.7-k2
firmware-version: 5.6-8
bus-info: 0000:06:00.0
  • pci3#1 - add-in network adapter on PCI Slot 3 Port 1
[root@fedora-14-r710 ~]# ethtool -i pci3#1
driver: igb
version: 2.1.0-k2
firmware-version: 1.5-1
bus-info: 0000:07:00.0
  • pci3#2 - add-in network adapter on PCI Slot 3 Port 2
[root@fedora-14-r710 ~]# ethtool -i pci3#2
driver: igb
version: 2.1.0-k2
firmware-version: 1.5-1
bus-info: 0000:07:00.1

Expected Results

All the add-in PCI network interfaces should get named as per their physical location in the system motherboard.
