You also really should document *what* is required of userspace here. You're kinda saying this needs to be implemented, but not saying what needs to be done. I can't even tell - what does it really have to do? Don't you implement most of it in patches 3 and 4 anyway in the kernel? johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
