[Bug 1090002] Re: biosdevname gives name of device as rename7 in Quantal

[jordanh]

I think this has something to do with the HP SMBIOS entries.

Incidentally it looks like there is a BIOS bug as Type 9 Slot structures
all point to 0000:00:00.0 (an actual device) not ffff:ff:1f.7 for an
inactive device.

Type 209 lists:
	NIC 1: PCI device 04:00.0, MAC address 00:17:A4:77:3C:00
	NIC 2: PCI device 04:00.1, MAC address 00:17:A4:77:3C:02
	NIC 3: PCI device 04:00.2, MAC address 00:17:A4:77:3C:08
	NIC 4: PCI device 04:00.3, MAC address 00:17:A4:77:3C:0A
	NIC 5: PCI device 04:00.4, MAC address B4:99:BA:A6:B9:18
	NIC 6: PCI device 04:00.5, MAC address B4:99:BA:A6:B9:1C
	NIC 7: PCI device 04:00.6, MAC address B4:99:BA:A6:B9:19
	NIC 8: PCI device 04:00.7, MAC address B4:99:BA:A6:B9:1D
	NIC 9: PCI device 05:00.0, MAC address 00:17:A4:77:3C:04
	NIC 10: PCI device 05:00.1, MAC address 00:17:A4:77:3C:06
	NIC 11: PCI device 05:00.2, MAC address 00:17:A4:77:3C:0C
	NIC 12: PCI device 05:00.3, MAC address 00:17:A4:77:3C:0E
	NIC 13: PCI device 05:00.4, MAC address B4:99:BA:A6:B9:20
	NIC 14: PCI device 05:00.5, MAC address B4:99:BA:A6:B9:24
	NIC 15: PCI device 05:00.6, MAC address B4:99:BA:A6:B9:21
	NIC 16: PCI device 05:00.7, MAC address B4:99:BA:A6:B9:25

type 221 lists:
	NIC 1: PCI device 04:00.2, MAC address 00:17:A4:77:3C:08
	NIC 2: PCI device 04:00.3, MAC address 00:17:A4:77:3C:0A
	NIC 3: PCI device 05:00.2, MAC address 00:17:A4:77:3C:0C
	NIC 4: PCI device 05:00.3, MAC address 00:17:A4:77:3C:0E

smbios is using both 209/221 so it is assigning index 
3/1 to 00:17:a4:77:3c:08
4/2 to 00:17:a4:77:3c:0a
11/3 to 00:17:a4:77:3c:0c
12/4 to 00:17:a4:77:3c:0e

Not sure why the others are getting renumbered in the process though

Bug description:
  In Quantal kernel biosdevname feature is not working as it suppose to
  be. On hardware we are seeing an issue where few of the network
  interface names are named as rename7 etc.. while biosdevname -d
  utility provides the correct biosname while kernel name have been
  messed up. There are total 16 network interfaces on the server which
  are ALOMs for Emulex card connected to system.

  It seems this issue is a race condition and will get fixed in Fedora
  18. But having fix in Quantal will help also.
