Will make a patch and come back once I'll have more informations. Thanks, Arnaud -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

Bug#673107: kirkwood: TCP checksum errors when using MTU 9000
Package: linux-2.6 Version: 2.6.32-45 A user on the Kirkwood platform reported TCP checksum errors when using MTU 9000: http://forum.qnap.com/viewtopic.php?f=147&t=59281&p=266527#p266527 This has been previously discussed: http://lists.debian.org/debian-arm/2009/11/msg00087.html iirc a patch went into the kernel to set the limits for the various platforms (orion, kirkwood)... or maybe it was just discussed and never went in. Arnaud, can you investigate whether this patch really went in or what's going on here? -- Martin Michlmayr http://www.cyrius.com/ -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
