Hmm. While this sounds more sensible, is it needed? And what does the
windows driver do?
I think there are two kind of LEDs - one that comes on and off with the
rfkill switch; Larry or Herton makes the 2nd one, if there is one, blink
while there is traffic (and stay steady on otherwise).
I have used this driver on the YeeLoong netbook(only support Linux),
there is only one LED for rtl8187, when there is traffic, it blinks
perfectly, but If press the hotkey to turn off the rf, the network
interface is down, but the LED is still light, then, the users may
mistakenly think the hotkey or rfkill support doesn't work or simply
think the interface is still on. So, that's why we may need to fix it.
My laptop (a Toshiba one) has the other kind of LED - the LED only comes on and
off in relation to the rfkill switch, and does not blink with traffic. I think
Herton or Larry has some devices with both types.
Hmm, I seem to have the impression that there is code somewhere for switching a
singular LED's behavior of the driver between one or the other, by echo'ing into
sysfs or some other trickery? Or would that be a desired approach if that's not
done at the moment?
My rtl8187 devices are both external USB sticks, thus they have no interaction
with a radio-kill switch. I will test your patch to make sure it does no harm to
my system.
I think the commit message should be revised. A simple statement like "the LED
does not turn off when the rfkill switch is off" should be sufficient.
