Feature #311365, revision 6
  Title: Include 71-biosdevname.rules to rename network interfaces based
  on chassis labels
   
  openSUSE Distribution: Unconfirmed
  Priority
      Requester: Important
   
  Requested by: Narendra K - (narendra_k)
  Developer: jordan hargrave (jhargrave)
  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 labeled on the server chassis. This
  issue is seen on Dell PowerEdge 10G above. This feature addresses this
  issue by renaming network interfaces based on their location on the
  system motherboard.
  The naming policy it suggests are as follows -
  Embedded devices: em<port> Add-in PCI cards: pci<slot>p<port>_<virtual
  function instance>
  Please refer to "Consistent Network device naming-Name network
  interfaces to match chassis labels"
  (https://features.opensuse.org/310896).
   
  Business case (Partner benefit):
  openSUSE.org: This allows system administrators to refer to the network
  interfaces by names based on their location on the motherboard. The
  naming becomes deterministic and there is no state such as HWADDR
  embedded into the configuration files.
   
  Discussion:
  #1: Narendra K - (narendra_k) (2011-03-01 16:28:05) 
  This request is for the inclusion of 71-biosdevname.rules which define
  how the rename happens. 71-biosdevname.rules looks like this -
  SUBSYSTEM!="net", GOTO="netdevicename_end" KERNEL!="eth*", GOTO="
  netdevicename_end" ACTION!="add", GOTO="netdevicename_end" NAME=="?*",
  GOTO="netdevicename_end"
  # kernel command line "biosdevname={0|1}" can turn off/on biosdevname
  IMPORT{cmdline}="biosdevname" ENV{biosdevname}=="?*", ENV
  {UDEV_BIOSDEVNAME}="$env{biosdevname}" # ENV{UDEV_BIOSDEVNAME} can be
  used for blacklist/whitelist # but will be overwritten by the kernel
  command line argument ENV{UDEV_BIOSDEVNAME}=="0", GOTO="
  netdevicename_end" ENV{UDEV_BIOSDEVNAME}=="1", GOTO="
  netdevicename_start"
  # uncomment the next line for biosdevname to be off by default # GOTO="
  netdevicename_end"
  LABEL="netdevicename_start"
  # using NAME= instead of setting INTERFACE_NAME, so that persistent #
  names aren't generated for these devices, they are "named" on each
  boot. PROGRAM="/sbin/biosdevname --policy physical -i %k", NAME="%c",
  OPTIONS+="string_escape=replace"
  LABEL="netdevicename_end"
   
+ #2: Mark Cowley (mcowley) (2011-03-01 10:47:48) (reply to #1)
+ Yikes, that is pretty jumbled together and hard to read. Could you
+ please resubmit it formatted? HTML tags can be used, and consider just
+ using "pre" for your already formatted text. Or if that doesn't work,
+ you can email a formatted document to me and I will copy it over here.
