I was trying to understand ipsec code and have come accross a doubt.

Can anyone explaing how the kernel will call "ipsec_tunnel_start_xmit" of
virtual device [ipsec0-4]. please guide me how this done and let me know
where can i find more doucments

In the code the comment says "ipsec_tunnel_start_xmit" will be called
from dev_queue_xmit() and my understanding is dev_queue_xmit()
will always calls hard_start_xmit of physical device.

Thanks in Advance.
