I will try to explain it once again. It's really easy. Think of b43 having two independent registers for rfkill. (the actual hardware is different, but that doesn't matter. It's a driver internal implementation detail). One of these registers is readonly and it does indicate the physical rfkill button state. If that register indicates BLOCK, we can't do anything about it. The radio is blocked. However, we can still write to the second register and turn the radio off through that, too. We can also write to the second register to turn the radio on, _but_ it won't physically turn on until the physical button is pressed and the first register changes to Unblocked. So you say that rfkill should only be notified about changes in the first read-only hardware intication bit? If that's the case, it would be possible to turn the radio off through mac80211 calls (using the read-write register), but still have rfkill think it's unblocked. -- Greetings Michael. -- 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
