Lenovo ThinkPad x201i has two rfkill buttons. One soft: Fn-F5. Second hard: small switch on left case side. With RFKILL_CONFIG == "is not set" this two buttons became inactive. They do not has any influence to adapter\drivers state. This patch give ability disable rfkill sub-system by means to pass special module parameter. Example from real life. Some company want to make inactive rfkill SW+HW buttons on some company notebooks. For this, you advise to recompile kernel. 2. One more thing, why this patch is necessary. You advise to use urfkilld. But this is doesn't help in case of external USB WIFI devices. Turn on(off) HW button will be effect on all WIFI devices, even external. rfkill kernel subsystem will bring all cfg80211 devices to software lock. See: net/wireless/core.c for rfkill. I do not think, that urfkilld will help. -- 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
