All the network devices are strored in a linked list
with the head node dev_base. 

dev_base is a global variable of type struct net_device *
and should be accessed using a read/write lock, dev_base_lock.
(If in uniprocessor machine lock doesn't matter).

Parsing through the list u can find the appropriate network
device ( one way is identifying by the name such eth0,.. 
in the name field).

And then can make use of the function pointer 
hard_start_xmit in the structure net_device.

Hope this helps you....
