Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hello all, I want to know what is use of dev_queue_xmit_nit function in dev.c file? Also why it calls following statement ptype->func(skb2, skb->dev, ptype); Also why skb2 is created by cloning skb? Acually i trace TCP packets and found that control goes from neigh_resolve_output to directly dev_queue_xmit_nit and then to HW driver 8139too.c? I want to know why it not goes from dev_queue_xmit? I place printk statments and found after dev_queue_xmit_nit control moves to network interface driver? Help to understand the control packet path. Thanks in advance. linux_lover
