Add a new "LED" target to iptables, which allows LEDs to blink in
response to matching rules.
I did not have a look in deep into your patch but the first questions
that comes to my mind is, how many people can benefit from this LED
target? What is its real application?
Well granted its purpose is somewhat trivial, but if you do have
devices on your system that appear in the LED class it could be quite
useful.
Linux running on an embedded router for example, could blink specific
LEDs on the device's front panel depending on the traffic being
routed. You wouldn't be limited to one LED per interface either, you
could have an LED dedicated to OpenVPN traffic only for instance. Or
you could have a couple of LEDs for different classes of traffic,
which would tell you at a glance whether your device is being hammered
by HTTP traffic or BitTorrent transfers.
Hopefully once more devices start appearing in the LED class, having
a target like this will help people put them to good use.
Cheers,
Adam.
