Subject: Which function at link layer sends packet?
Date: Thu, 3 Feb 2005 18:48:19 +0530 [thread overview]
Message-ID: <1d55641b05020305182d423c57@mail.gmail.com> (raw)
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.
