> We already have different support for blinking in LED subsystem. Lets use that.
You are assuming we have full software control of the LED, we can turn
it on and off. That is not always the case. But there is sometimes a
mode which the hardware blinks the LED.
Being able to blink the LED is useful:
ethtool(1):
-p --identify
Initiates adapter-specific action intended to enable an
operator to easily identify the adapter by sight. Typically
this involves blinking one or more LEDs on the specific network
port.
Once we get LED support in, i expect we will make use of this blink
mode for this ethtool option.
