Comment 6 for bug 267875

In speaking with the kernel team, I understand that this was a deliberate change to harmonize the iwl* drivers with a new generic rf_kill interface, /sys/class/rfkill. It appears that the correct interface now for toggling/querying antenna state is /sys/class/rfkill/rfkill<n>/state (though back-associating this with a network interface is extremely sysfs-y). I'd like to get hard confirmation of this from the kernel team that this is the right interface, but in the meantime since it's an easy change I'm going to implement that in acpi-support.
