Public bug reported:

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.
