[Bug 1455871] Re: biosdevname isn't giving interface names as expected

Tue Jun 23 20:30:43 UTC 2015

Note that, differently from what was request in the BUG description, I
can't back port newer version to LTS Ubuntu Versions. I have to find
commits that were responsible for fixing erratic behaviour and make sure
all versions are fixed and, possibly, work together with the core team
to upstream version for Willy (Ubuntu development version nowadays).

Could you please provide:

- Server Type
- HBA Type
- Kernel Version

I could NOT reproduce this behaviour in a Proliant server with "mlx4_en:
Mellanox ConnectX HCA Ethernet driver v2.2-1 (Feb 2014)".  So I'll rely
on feedbacks in this case for proposing the SRU.

For now I have back-ported the following upstream commits:

commit 47da4e4e399c7455b282e3dae03de28519dcb166
Author: Jordan Hargrave <Jordan_Hargrave at dell.com>

    Add dev_port attribute for new Mellanox driver

    Add port code for Mellanox driver

commit f3e6790b7986a4f9dd4a407901717ef8de3cbbc6
Author: Jordan Hargrave <Jordan_Hargrave at dell.com>
Date:   Tue Feb 25 16:35:40 2014 -0600

    Add port structure to PCI device, handle multiple ports per BDF
(Mellanox)

commit cee3f7b101fb22540e2f92067a5c49d3f817e441

    Scan for devid for Mellanox cards

commit 70d82c269a335cf8f781f347b3708283d63ce213
Author: Jordan Hargrave <Jordan_Hargrave at dell.com>
Date:   Wed Oct 16 15:12:06 2013 -0500

    Stop reading VPD data once VPD-R section has been read
    Mellanox cards were taking too long to read entire VPD

AND Will inform a PPA to be tested soon.

Thank you

Rafael Tinoco

Title:
  biosdevname isn't giving interface names as expected

Status in One Hundred Papercuts:
  Confirmed
Status in biosdevname package in Ubuntu:
  Confirmed

Bug description:
  We see an issue with the biosdevname package that comes with ubuntu
  14.04.2 package version 0.4.1-0ubuntu6.1.

  There is two issue that we see with Mellanox Card that include two ports:
  1- Both ports aren't given interface names with format of "p<num>p<num> (e.g. p514p1) as expected.
  2- Second port isn't given "BIOS device" at all.

  After update the biosdevname to version 0.6.2 we don't see the issue (
  please see below the output of the biosdevname before and after the
  update).

  Could please update the version of the biosdevname package to fix this
  issue.

  Output from "biosdevname -d" for biosdevname 0.4.1-0ubuntu6.1, "BIOS device" and "Kernel name" aren't the same.
