Thanks!
The reason i am studying the code is because I have created virtual
ethernet devices - similar to what Rubini has described, but with the
facility to xmit *and* rcv packets. I do this using a new packet type
defined thru dev_add_pack() which points to my 'veth_recv'.
Currently i have created the devices as character devices because of the
support for /dev/vethdev kind of entries. I am now modifying them to
behave similar to network drivers (struct net_device, SIOCDEVPRIVATE,
register_netdev() etc...)
I was looking at various 'pseudo' network device drivers to understand how
they provide ioctl interfaces for creation of multiple devices (like
veth0, veth1, veth2..) since they obviously cannot be 'probed' by the
kernel at bootup.
My 'chicken and egg' problem is:
How do I provide an ioctl interface to the virtual devices which allows
creation, deletion, configuration of these devices when i *havent* yet
created/registered even a single virtual device?
Any suggestions?
Regards,
Amit
