Implementing ioctl in network drivers

Hi
I would like to implement ioctl calls from ifconfig in my network driver. How do I approach it? I was seeing the code from e100.c and it uses just the following code...

static int e100_do_ioctl(struct net_device *netdev, struct ifreq *ifr, int cmd)
{
struct nic *nic = netdev_priv(netdev);

return generic_mii_ioctl(&nic->mii, if_mii(ifr), cmd, NULL);
}

Any clue what is it doing? Is there any other way to implement ioctl calls?

Hi,

see the followink link for a good explanation about linux network drivers (chapter 17)
