#68233 — Bug#970722: linux: Igc driver has /proc/net/dev stats issue

Source: linux
Version: 5.8.10-1
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

I use Intel I225-V Ethernet controller with igc driver.
But it has /proc/net/dev stats issue.
For example Receive and Transmit bytes, packetes are all 0.

$cat /proc/net/dev
Inter-|   Receive                                                |  Transmit

0    0    0    0     0       0          0

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   * What was the outcome of this action?
   * What outcome did you expect instead?

There were some refactorings in upstream up to v5.9.1 in the igc
driver. Can you check, does the issue still persist in 5.9.1-1  as
currently in unstable?

I tried Linux 5.9.1-1 in unstable.
Receive and Transmit bytes, packetes are not 0,
but they don't appear to be increasing enough.

Can you check, is cherry-picking 6b7ed22ae4c9 ("igc: Fix returning
wrong statistics") fixing this issue?

Have a look at
https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#s4.2.2
witht the attached patch.

Does this helps? Otherwise I can look if I can provide you a temporary
build with the patch.

Salvatore

https://people.debian.org/~carnil/tmp/linux/fix-igc-driver-stats/

contains temporary (and unsigned!) binary builds. If you can trust
them then, they would contain the mentioned patch applied.

They furthermore are as well alrady based on 5.9.8 upstream instead of
5.9.6 as this is pending for the next unstable upload.

Salvatore

I tried your build and the issue seems to be solved.
