In that function it goes upto ptype->func(skb2, skb->dev, ptype); and then i am not getting which functions get called but then i found call goes to ethernet driver to NIC card. Does that mean above statement calls hard_start_xmit? Then i reboot my linux RH9 with 2.4.24 kernel PC and again ping to 192.168.1.1 and found that packet transmission is not going through dev_queu_xmit_nit but from dev_queue_xmit to hard_start_xmit. regards, cranium.
