Hi
I am getting kernel messages = "protocol 0000 is buggy, dev eth0" in my kernel while calling dev_queue_xmit(skb);. The packet is successfully tranmitted on the wire but these messages are keep coming on the console.
I am not sure what is the exact modification needed to avoid these kernel messages. Can you someone help on this.
Exact code I have in my driver code: tx_len is length of the packet to be transmitted tx_packet is the pointer to packet container.
skb = dev_alloc_skb(tx_len); if (skb == NULL) return -1; skb_put(skb,tx_len);
memcpy(skb->data, tx_packet, tx_len);
skb->dev = dev_my_device;
skb->len = tx_len;
dev_queue_xmit(skb); dev_put ( dev_my_device); return 0;
You didn't set skb->network_header. Bjørn
