cat /sys/class/net/eth0/statistics/tx_bytes always 0 [atl2 driver]

Hi froverio,

Care to do a quick test. The latest Alpha5 for the upcoming Intrepid Ibex was just released. I'd like to know if this will still be an issue with the upcoming release. It has an updated 2.6.27 kernel. You should be able to test using a LiveCD - http://www.ubuntu.com/testing/intrepid/alpha5 . Please let us know your results. Thanks.

Thanks for your answer, with intrepid live CD. I have the same problem.

And on Gusty 7.10 32 bits kernel 2.6.22.14-generic it's same. Perhaps my network card is not fully qualified.

My Network Card is an "Atheros L2 Fast Ethernet" and a have always the problem on Intrepid.

Hi froverio,

Per the kernel team's bug policy, can you please attach the following information. Please be sure to attach each file as a separate attachment.

* cat /proc/version_signature > version.log
* dmesg > dmesg.log
* sudo lspci -vvnn > lspci-vvnn.log

For more information regarding the kernel team bug policy, please refer to https://wiki.ubuntu.com/KernelTeamBugPolicies .

I myslef do not see this issue here on my system:

ogasawara@emiko:~$ cat /proc/version_signature
Ubuntu 2.6.27-10.20-generic
ogasawara@emiko:~$ cat /sys/class/net/eth0/statistics/tx_bytes
23130280

Thanks again and we appreciate your help and feedback.

cat /sys/class/net/eth0/statistics/tx_bytes return always 0

After researching your problem, it appears that the driver you are using is from 2.6.28 which is too recent for inclusion in intrepid.
There is a bug as you describe in the early versions of that driver.
Please clarify where the driver came from so we can proceed with
a solution.

I have placed a test package in my public directory for this bug. Please report back your results so we can include this fix in the next update.

For 32bit:

http://people.ubuntu.com/~lieb/i386/ linux-image-2.6.27-11-generic_2.6.27-11.21~lp268622lieb1_i386.deb

For 64 bit:

http://people.ubuntu.com/~lieb/amd64/ linux-image-2.6.27-11-generic_2.6.27-11.21~lp268622lieb1_amd64.deb

Please also report back which package you tested.

Note: these packages are solely for testing purposes. We recommend that you un-install this package once your testing is complete and wait for a supported update.

The package linux-image-2.6.27-11-generic_2.6.27-11.21~lp268622lieb1_amd64.deb solve the problem, is a good job, thanks.

SRU Justification

Impact: Add missing byte count accumulation for transmit packets
This patch is copied from the upstream atl2 driver patch in upstream

commit e2f092ff9bf2ab515c14d2208b5f08c7d389d5d2. It is *not*
this patch since the ubuntu/atl2 driver is of different vintage.

The necessary patch is already in Jaunty 2.6.28

Patch: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-intrepid.git;a=commit;h=8e640a9df6bfd5d31fddd3183a1394c263f60057

Test case: See bug description. Reporter confirmed patch

Accepted linux into intrepid-proposed, please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Hi froverio,

It would helpful if you (or anyone else using the atl2 driver hit by this bug) could test the kernel in intrepid-proposed and verify that /sys/class/net/eth0/statistics/tx_bytes is reporting information. Thanks!

Hello,

The verification that /sys/class/net/eth0/statistics/tx_bytes is reporting information is OK on my intrepid 64 Bit fresh install after a intrepid-proposed update.

froverio@desktop:~$ cat /proc/version_signature
Ubuntu 2.6.27-11.23-generic
froverio@desktop:~$ cat /sys/class/net/eth0/statistics/tx_bytes
189318

Thanks.
