Then the hard one isn't actually a hard button. The typical hard button is a switch that is wired directly to the mini-pcie slot and enables/disables the card via a GPIO line on the card. This is reported as a hard even *through the wifi card*. Nothing you can do about it in those cases. > This patch give ability disable rfkill sub-system by means to pass > special module parameter.

See: net/wireless/core.c for rfkill. I do not think, > that urfkilld will help. No, it will not. It doesn't work that way. A hard switch in one wifi device doesn't impact any other devices unless you use urfkilld or RFKILL_INPUT. 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
