Hello arges,

I updated the patch pointing to the right upstream commit, also i added the required dep3 headers
on the patch.

Could you please re sponsor-patch this one?

Title:
  [SRU] biosdevname returns identical names for two different devices.

Status in “biosdevname” package in Ubuntu:
  In Progress
Status in “biosdevname” source package in Saucy:
  In Progress
Status in “biosdevname” source package in Trusty:
  In Progress

Bug description:
  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 fix from upstream project.

  Origin: upstream, http://linux.dell.com/cgi-bin/gitweb/gitweb.cgi?p=biosdevname.git;a=commit;h=0bc6ce6d8da61153e7bfd1c3444ab06c0c83d0af
  Bug: 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
