Date: Mon, 3 Sep 2007 22:57:56 +0200 From: Francois Romieu <romieu@...zoreil.com> To: Shane <shane@....ca> Cc: netdev@...r.kernel.org Subject: Re: r8169: jumbo frames Shane <shane@....ca> : [...] > Just wanted to report that when setting a mtu of 4074, I'm > getting slow Samba performance with an r8169 based NIC even > with the fix for this posted here applied. all dmesg shows > is: > NETDEV WATCHDOG: eth0: transmit timed out It is a bit terse: - which kernel ? - which fix exactly (Message-Id or URL) ? The one I sent the 29 of 08/2007 or something else ? - which chipset (lspci -vvx) ? Fwiw, I have rediffed the patchkit against 2.6.23-rc5. See: http://www.fr.zoreil.com/people/francois/misc/20070903-2.6.23-rc5-r8169-test.patch or: http://www.fr.zoreil.com/linux/kernel/2.6.x/2.6.23-rc5/r8169-20070903/ If you have not done so already, I would appreciate that you try to reproduce the problem with a 1500 bytes MTU with/without the aforementioned patch. > The mtu value is due to Windows workstations which support > this value and 9k MTU but the r8169 doesn't appear to like > 9k although that's where I'd like it to be on this network. The 8169 will not fly above 7200, be it on Linux or Windows. :o/ -- Ueimor - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
