Hello, In a LAN i have 2 pcs host1 with 10.0.2.10 and host2 with eth0:10.0.0.100 and eth1:192.168.1.1 Both are connected to switch. what i observe that when i ping from 10.0.2.10 to 192.168.1.1 then packet is sent through dev_queue_xmit_nit. 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. -- Kernelnewbies: Help each other learn about the Linux kernel.
