This is becoming a FAQ... see net/core/dev.c, line 907 on 2.5:
/* skb->nh should be correctly set by sender, so that the second statement is just protection against buggy protocols. */ skb2->mac.raw = skb2->data;
if (skb2->nh.raw < skb2->data || skb2->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; }
