[New: openFATE 310896] Consistent Network device naming-Name network interfaces to match chassis labels
Feature added by: Narendra K - (narendra_k) Feature #310896, revision 1 Title: Consistent Network device naming-Name network interfaces to match chassis labels openSUSE-11.4: Unconfirmed Priority Requester: Important Requested by: Narendra K - (narendra_k) Partner organization: openSUSE.org Description: On a Dell PowerEdge server with multiple add-in cards, the naming of the network interfaces is non-deterministic. This results in 'eth0' not mapping to "Embedded NIC 1" as labelled on the server chassis. This issue is seen on Dell PowerEdge 10G above. This feature addresses this issue by renaming network interfaces based on the following policy as discussed in the Linux Plumbers Conference - http://marc.info/?l=linux-hotplug&m=128892593821639&w=2 Embedded devices: em<port> (em => ethernet-on-motherboard) Add-in PCI cards: pci<slot>#<port>_<virtual function instance> On a PER710 with 4 Lan-On-Motherboard interfaces and a dual port add-in network controller, the interface names would look like - Onboard interfaces - em1 em2 em3 em4 eth0 Interface names for the dual port add-in controller on pci slot 2 pci2#0, pci2#1 If the second port has virtual functions enabled - pci2#1_0, pci2#1_2 ... etc Biosdevname, which is a Dell developed utility can suggest these names for the kernel ethN names. This needs to be used as a udev helper utility.

Test Case: With this change - 1.ifconfig -a would show emN names for onboard interfaces. 2. em1 should correspond to the interface labelled 'Gb1' on the chassis label, em2 to 'Gb2' etc. This can be tested by ethtool -p em1 (Blinks the interface) 3.

There is no state such as HWADDR embedded to achieve persistent naming Business case (Partner benefit): openSUSE.org: When there are multiple network interfaces in a system (onboard + add-in interfaces), eth0 does not always map to the 'Embedded NIC 1' as labelled on system chassis.

This results in 'eth0' not mapping to "Embedded NIC 1" as labelled on the server chassis. This issue is seen on Dell PowerEdge 10G above. This feature addresses this issue by renaming network interfaces based on the following policy as discussed in the Linux Plumbers Conference - http://marc.info/?l=linux-hotplug&m=128892593821639&w=2 Embedded devices: em<port> (em => ethernet-on-motherboard) Add-in PCI cards: pci<slot>#<port>_<virtual function instance> On a PER710 with 4 Lan-On-Motherboard interfaces and a dual port add-in network controller, the interface names would look like - Onboard interfaces - em1 em2 em3 em4 Interface names for the dual port add-in controller on pci slot 2 pci2#0, pci2#1 If the second port has virtual functions enabled -pci2#1_0, pci2#1_2 ... etc Biosdevname, which is a Dell developed utility can suggest these names for the kernel ethN names.

Test Case: With this change - 1.ifconfig -a would show emN names for onboard interfaces. 2. em1 should correspond to the interface labelled 'Gb1' on the chassis label, em2 to 'Gb2' etc. This can be tested by ethtool -p em1 (Blinks the interface) 3.
