Hi Emmanuel,

Actually to properly handle led_mode=3 option is not as easy as it seems.
Even if I initially turn of the LED in case of led_mode=3, it still gets
turned on after doing
# ifconfig wlan0 down && ifconfig wlan0 up

Maybe if I have more time later I can investigate further on how to
avoid this behaviour. (the LED trigger is set to none according to
sysfs) Or you have an idea on how to stop this behaviour?

Otherwise I would suggest that you apply the patch that I posted on
bugzilla (attached) that fixes sysfs handling. It is then easy to keep
the LED on or off as desired using simple shell scripts.

Thank you,
Hubert
