Thats right ! But what if my code has to have the ability to be compiled
into the kernel as well as a module? In that case (when it is compiled
into the kernel), where can i call my 'init' function?

I was referring to the device, so it *does* create tap0.
I need a method which will do the following:
1. I have 2 drivers which depend on 'basic functionality XYZ' inside the
kernel.
2. Both the drivers can be compiled into the kernel or be built as
modules.
3. I have added the following to drivers/net/Config.in
---------------------------------------
[] XYZ functionality (CONFIG_XYZ)
< > Driver 1 (CONFIG_DRIVER1)
< > Driver 2 (CONFIG_DRIVER2)
---------------------------------------
4. Now, when I select CONFIG_XYZ in make xconfig, i need to call
xyz_init() regardless of whether CONFIG_DRIVER1 and CONFIG_DRIVER2 are
compiled in or not.
*****Question******
Where should the following statements go:
--------------------------------------
#ifdef CONFIG_XYZ
xyz_init(void);
printk(KERN_DEBUG "xyz_init called!!\n");
# ifdef CONFIG_DRIVER1
driver1_init(void);
# endif
# ifdef CONFIG_DRIVER2
driver2_init(void);
# endif
#endif
---------------------------------------

The statement below is true.
The statement above is false.
