Where does the module parameter stored while loading a driver module with module parameter

Where does the module parameter stored while loading a driver module with module parameter.I need to automate such that if i load a module it will load with that parameter enabled. eg if I need to load a module net_dev.ko with a module parameter hw_enable=1 So I need to do-

modprobe net_dev hw_enable=1

to load it with that option But I want when I do-

modprobe net_dev

It will automatically take hw_enable=1 So for that where should i kept this module parameter in the kernel?

Options are provided in the configuration file for the module to be installed in the /etc/modprobe.d/ directory. So in your case if you create a file net_dev.conf in /etc/modprobe.d directory with the following line

options net_dev hw_enable=1

and you call modprobe net_dev, it should execute modprobe net_dev hw_enable=1
