Have you ever seen kernel build system? If you want to add compile-time options, that's what the config thing is for. Each directory can have a file (Configure, or something like that) where it describes compile-time options it wants. There can then be set by make menucoding or make qconfig (or the other *config targets). However, the above option should NOT be compile-time. Either implement appropriate IOCTL so it can be set by ifconfig, or at least implement driver parameters (there are some macros like mod_param to declare them -- i don't recall which variant is current, as there are some obsolete ones as well). -- Jan 'Bulb' Hudec <bulb@xxxxxx>
