Description Ivan Vecera 2008-12-03 11:37:53 UTC

Description of problem:
I have a system with a network card handled by r8169. There is no problems with connectivity but if I try to run 'ifconfig ethN' then incredible (random) number of RX dropped packets is returned.

Version-Release number of selected component (if applicable):
2.6.18-123.el5

How reproducible:
Always

Steps to Reproduce:
1. run ifconfig to retrieve information about ethernet device
  
Actual results:
Incredible number of RX dropped packets is returned
E.g.:
...
RX packets:4123269 errors:0 dropped:62865594978225 overruns:0 frame:0
...

Expected results:
The driver should return correct number of RX dropped packets.

Additional info:
The following upstream commit should correct this issue.

Comment 5 Zhang Kexin 2009-07-29 08:15:09 UTC

Hi Ivan,

could you help test the rhel5.4 kernel for us? since finding a suitable machine
is not easy.
patch goes in kernel 2.6.18-141, and latest rhel5.4 kernel is 2.6.18-160.

thanks.

Comment 6 Ivan Vecera 2009-07-29 11:24:22 UTC

Hi Zhang,
I tested 5.4 kernel on all my machines with Realtek's NICs and the issue is solved for 5.4.
