VIA Rhine ethernet driver bug

VIA Rhine ethernet driver bug

[Udo van den Heuvel]

Hello,

I posted about the VIA Rhine ethernet bug to the LKML but received the
suggestion to also post here.
Let me explain about the bug, it gives messages like:

Apr  8 18:51:08 epia kernel: eth1: Oversized Ethernet frame spanned multiple
buffers, entry 0x9 length 0 status 00000600!
Apr  8 18:51:08 epia kernel: eth1: Oversized Ethernet frame cca77090 vs
cca77090.

buffers, entry 0xa length 0 status 00000400!

cca770a0.

Apr  8 18:51:08 epia kernel: eth1: Oversized Ethernet frame cca77070 vs
cca77070.
Apr  8 18:51:08 epia kernel: eth1: Oversized Ethernet frame spanned multiple

Apr  8 18:51:08 epia kernel: eth1: Oversized Ethernet frame cca77080 vs
cca77080.


Most of the time the ethernet connection is gone and needs and ifconfig
down/up or reboot to make it work again.
I see this error on a VIA EPIA CL-6000 board. Using google I see the
mentionings of the error messages in relation to VIA Rhine go back to 1999.
The other side of eth1 is an Alcatel Speedtouch Home. With different
firewall hardware (Tulip DT5/xxx but same Alcatel) I did not see the errors.

Any ideas? A patch to gather more info so the bug can be fixed?
Etc?

Please post!

(the ERR value has a relation to the bug? I just rebooted the box and the

It's been a while since I looked into this, but here's what I remember:
This is not supposed to happen. Because this is so peculiar, I talked
it over with VIA, and they want to know whether their own driver makes
any difference. I relayed that request to you, but I don't remember
ever getting a report back. Did I miss something?
