Francois, Using the latest patch you provided in the previous e-mail under 2.6.22-rc3 I still see data corruption after I dropped the entire network to MTU 1500. (The receive corruption is way more frequent than under 2.6.18.) I'll attempt to find out what caused the link detection to stop working. Do you have any idea about the data corruption? I can easily put in trace anywhere in the driver if you'd like to see any output. My latest build was without NAPI support, and running with or without it didn't seem to affect the receive corruption.

Francois Romieu <[EMAIL PROTECTED]> : [...] Andrew, have you had any time to do some testing with an uniform 7200 bytes MTU through your LAN ? You will find a backport of the r8169 driver for the 2.6.18 kernel at http://www.fr.zoreil.com/people/francois/backport/r8169/20070604-00 Could you do a binary search of the patch which breaks the link detection ? From a different report that I have received, the current testing branch of the 8169 driver would improve things for MTU beyond 1500 bytes: nailing down your broken link regression would be a welcome improvement. If you are confortable with git, you can do a git bisect after pulling the branch 'r8169-backport-test-20070604' at: git://electric-eye.fr.zoreil.com/home/romieu/linux/linux-2.6-out (please do the initial clone from elsewhere if you use git, thanks) -- Ueimor
