Created attachment 365488 [details] dmesg and lspci -v output Description of problem: tx offloading on the r8169 can be enabled by using ethtool, and this appears to succeed, but silently outgoing traffic is disabled. I noted this by seeing that no DNS queries were resolved. Version-Release number of selected component (if applicable): Linux lenovo.badmuts.org 2.6.30.8-64.fc11.x86_64 #1 SMP Fri Sep 25 04:43:32 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded How reproducible: always Steps to Reproduce: 1. ethtool -K eth0 tx on 2. nslookup www.gnu.nl 3. Actual results: The ethtool command reports no error. The nslookup command seems to hang. Maybe only UDP traffic is disabled, or all traffic may be affected. Expected results: Transmit offloading enabled, traffic continues normally. Additional info: System is a Lenovo SL500 laptop. Network device is RTL8168c/8111c according to the kernel, but lspci reports RTL8111/8168B. It appears this is a problem caused by small differences between different versions of the Realtek 8168/8169/8111: http://patchwork.ozlabs.org/patch/34203/
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

I tested it with 2.6.34-rc7 and get it working, may be it works since 2.6.34-rc4
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
