I thought I understood but I'm not so sure anymore. I applied the following patch to dev.c:

--- linux/net/core/dev.c.orig Sun Dec 30 00:31:43 2001
+++ linux/net/core/dev.c Sun Dec 30 00:33:27 2001

skb2->mac.raw = skb2->data;

- if (skb2->nh.raw < skb2->data || skb2->nh.raw > skb2->tail) {
+ if (skb2->nh.raw < skb2->data || nh.raw > skb2->tail) {
if (net_ratelimit())
printk(KERN_DEBUG "protocol %04x is buggy, dev %s\n", skb2->protocol, dev->name);
skb2->nh.raw = skb2->data;
This however gives compilation errors, 'nh' undeclared. So no buggy messages anymore :-)...

It's easy for me to generate these buggy messages (each raw transmission seems to produce them) so if there is anything I can try out I'll be happy to do it.

Kind regards,


P.S. I'm using a SuSE flavour of the kernel so I have to use the linux-2.4.16.tar.bz2 kernel with SuSE's suse-2.4.16-7.bz2 patches as there are no SuSE addaptations for the 2.4.17 kernel yet (at least last time I checked, i.e. yesterday).
