[Bug 1324558] Re: [SRU] biosdevname returns identical names for two different devices.

[Jorge Niedbalski]

** Description changed:

  SRU justification :
  
  The 'addslot' function can return the same value for two or more
  interfaces (same dev->index_in_slot), causing the interfaces on a given
  PCI slot get same port number. This could trigger a rename to a
  different name space (such as rename*) presented on LP: #1284043.
  
  Example problematic behavior:
  
  # biosdevname -i em1
  em1
  # biosdevname -i em2
  em3
  # biosdevname -i em3
  em4
  # biosdevname -i rename3
  em2
  
  Another user points:
  
  On first reboot the names are different. eth0 renamed to p4p1 and eth1 renamed to p4p2
  then on next reboot eth0 renamed to p4p1 and eth1 renamed to rename3
  
  Impact :
  
  Without this SRU users will experience erroneous output from biosdevname
  ( renamed interfaces) as noticed on LP: #1293633 and LP: #1284043
  
  Fix :
  
- Apply patches from upstream
- https://bugzilla.redhat.com/show_bug.cgi?id=782145

  Test Case :
  
  1) Have one or more PCI ethernet cards attached
  2) Have one or more onboard ethernet cards available.
  3) Run biosdevname -d and notice the renamed interfaces.
  
  If you get some rename* interfaces this bug isn't fixed, if you can see
  the correct bios hardware names associated with the interface, it's
  fixed.
  
  Regression :
  
  None expected
