Network Device Driver

[digvijay.gahlot]

Hi
I have written a network driver with help of Alexender Rubino's book.
My driver initialiation code works well and successfully initializes the net_device structure. The irq is to be allocated in the open function. My open method starts as:-

int netdriver_open(struct net_device *dev)
{
printk(KERN_DEBUG "Start of open method\n");
ssleep(10000);
...
Loading the module is successful. My interface is sn0. But when i try
# ifconfig sn0 192.168.1.1
SIOCSIFFLAGS: Invalid argument
is displayed.
There is no related message in /var/log/messages. The open method is not even called. Plz help

Can you check u have something like below code

struct net_device *dev

dev->open = netdriver_open; //used for calling file operation open()
