* 2.6.31 regression: e1000e jumbo frames no longer work: 'Unsupported MTU setting' @ 2009-09-26 11:16 Nix 2009-09-27 2:14 ` Alexander Duyck 0 siblings, 1 reply; 3+ messages in thread From: Nix @ 2009-09-26 11:16 UTC (permalink / raw) To: e1000-devel, linux-kernel; +Cc: netdev, bruce.w.allan [Bruce, you have changes in net-next in this area, so you might have a clue what's going on here.] In 2.6.30.x, I was happily bringing up the 82574L cards in one server like this: ip link set fastnet up mtu 7200 As of 2.6.31.x, what I see is this: spindle:/root# ip link set mtu 7200 dev fastnet RTNETLINK answers: Invalid argument [ 3380.261796] 0000:02:00.0: fastnet: Unsupported MTU setting As far as I can tell, all MTUs above 1500 now fail. 'Unsupported' or not, this used to work, and I'd certainly expect jumbo frames to be supported on a gigabit card! I can't see any terribly relevant changes to e1000e between 2.6.30 and 2.6.31, so I'm Cc:ing netdev on the offchance that this is something more generic (unlikely, as 7200-byte MTUs still work fine in 2.6.31 with the r8169 I'm typing this on, but that doesn't help if half the subnet is forced to use MTUs of 1500). (I'd bisect it but this machine has a weird halfassed IPMI implementation that can't be turned off and tends to take console I/O and throw it away, so I reboot it only when I have absolutely no choice, as if there's any filesystem problems it's often several hours of flailing before the damn thing can be coerced back up again.) .config: CONFIG_64BIT=y CONFIG_X86_64=y CONFIG_X86=y

It looks like the problem is that the 82574 and 82583 seem to have their max_hw_frame_size values swapped. You might try applying the patch below. I am not sure if it will apply since I hand generated it using the git patch that seems to have introduced the problem, and I am sending the patch through an untested account that may mangle the patch. I will see about submitting an official patch for this sometime next few days.

People with an 82574 who are using jumbo frames may well find their networks not coming up, if like me they set a bunch of properties in one /sbin/ip call. ------------------------------------------------------------------------------ Come build with us!
