The regulatory information is too dynamic to be placed in the kernel. And not all regulatory information is public: as I wrote in a previous message: I work for a company that has special regulatory permission to use channels outside those freely available with tx power of up to 4W. This is a legitimate use case that should not be forbidden by a new regdomain framework (I can always hack around this, but that's just a hack, not a clean solution). Regarding a user space daemon: keep in mind special use cases like NFSroot over WLAN. > 2. The regulatory database should be in an ASCII file for easy updating.

For me it is perfectly legal to use channel 14 in Europe with 4W tx power. I admit that this is a special interest, but nonetheless perfectly legal. -- Regards Joerg __________________________________ Yahoo!
