[Linux-ia64] adding new network device driver

[Gururaj Ananthateerta]

I have written a driver for a netwok deive. I want to add it in the kernel.
I have compiled the code with 2.4.0 patched with the latest patch. The new
kernel (my_kernel) contains my driver symbols. 

When I boot with new kernel my driver probe routine is not entered. 
Is there anyplace I need to inform the kernel about the existence 
of the new driver.

THis is on ia64 on RH7.1 and whole thing is on Lion.

Thanks
Guru

If it's a module, you simply mark your init function with __init, like so:

int __init my_driver_init(void)
{
	...
}

And then if it can be built as a module, put
module_init(my_driver_init);

at the end.  See most of the networking drivers for how they do this.

Then, at kernel build time, if your driver is built into the kernel
(CONFIG_XXXX=Y), it gets its initialization routine called during the kernel
startup.  If it's a module, it gets called when you insmod your driver.

Of course, all of this isn't specific to IA-64, so this probably isn't the
right list.

Thanks,
Matt

Updated Space.c and compiled the kernel. 
The proble is called and my device is identified and configured. But there
is some problem.
There are 2 ethernet devices (including mine) 1 is Intel EEpro100 and
mine (gigabit controller). When the kernel boots it recognizes my NIC and
EEpro100 NIC and hangs. I am unable to figure out whats going on. 
There is some confusions with  ehto and eth1 that I am unable to follow.
